What are the types of diffusion welding?

Diffusion welding, also known as diffusion bonding, could be a solid-state welding strategy that has utilization in metalworking. This strategy is competent in joining comparable as well as different metals. It works on the guideline of the solid-state dissemination, in which the particle of two solid, metallic surfaces scatter themselves with time.

This often ordinarily finishes at a hoisted temperature, around 50-75% of the supreme dissolving temperature of the materials. This strategy has commonly utilization in welding “sandwiches” of rotating layers of lean metal thwart, and metal wires or filaments.

Types of diffusion welding

As of now, the diffusion welding method has the most common utilization in joining high strength and hard heated metals inside the aerospace and atomic businesses.

Here are some types of diffusion welding:

Solid-state diffusion welding:

Diffusion bonding or diffusion welding of fabrics in the rigid state may be a handle for creating a solid link through the arrangement of the bond at nuclear levels.
Resulting in the termination of coupling surfaces because of the nearby plastic misshaping at lifted warmth which helps interdiffusion of at the exterior of sheets of joining fabric.

TLP (Transient Liquid Phase) Diffusion Welding:

Liquid state diffusion welding depends on the arrangement of a fluid stage at the bond line amid an isothermal bonding cycle. The fluid stage at that time imbues the base fabric and inevitably cements as a result of proceeded dissemination of the solute into the bulk fabric at a consistent temperature.
Subsequently, this method is called TLP (transient liquid phase) diffusion welding.

• Auto-vacuum welding:This is a strategy in which two solid metals joined to each other with the help of pressure. This technique is also called pressure joining.
• Hot Isostatic pressing: HIP (Hot Isostatic Pressing) is a fabricating handle, and has utilization in diminishing the porosity of metals, with the help of the combination of plastic misshaping, crawl, and diffusion welding. This method makes stride weakness resistance of the component.
• Laser welding
• Electron beam welding
• Forge welding

What are the advantages and disadvantages of diffusion welding?

Diffusion welding has numerous advantages, there are several downfalls to this technique.

Advantages:

• The reinforced materials represent the same physical as well as mechanical properties as the base fabric.
• The reinforced surface was tried through pliable testing.
• Diffusion weldingmakes clean joints, of all quality, and free from brokenness and porosity.
• Diffusion weldingpermits joining comparable and disparate materials, due to this, it is broadly applicable.
• Due to great measurement resilience, diffusion weldinghas utilization in delivering good accuracy and complex shapes.
• Additionally, the running expense is or maybe moo and the method is simple to approach.
• Plastic distortion decreases beneath diffusion.

Disadvantages:

• Even though the running expense is moo, the starting setup expense is pretty much high.
• Diffusion weldingis exceptionally time-consuming.
• The planning of the workpieces is basic and may be tough.
• The accessible gear limits the estimate of the weld.
• Diffusion weldinghas no application for mass production.
• The result is profoundly subordinate to the welding parameters, like temperature, weight, fabric surface wrap up, and the welding material.

What is the application of diffusion welding?

• It has utilization in welding factory material in aviation and atomic industries.
• Diffusion weldinghas utilization in welding titanium, and zirconium as well as beryllium metals and their alloys.
• It can weld nickel combinations like Inconel, Fashioned Udimet, etc.
• It has utilization in welding disparate metals, for example, Cu to Ti and Cu to Al, etc.

Ultrasonic welding

Ultrasonic welding has application in liquefying the workpiece by ultrasonic vibration contact warm and utilizing the grinding warm vitality and has creation at the contact surface of both workpieces to be welded. Warm vitality comes from the responding development of the workpiece on the other surface with a certain relocation or sufficiency beneath a certain weight.

Once the anticipated degree of heat holding is come to, the vibration will be halt, and at the same time, there still be a certain sum of weight applied on the two workpieces. These workpieces can cool and sets the parts that have fair been warmed, in this way shaping a near bond.

Fiction welding

Friction welding abbreviated as FRW could be a solid-state welding strategy that creates warmth via automatic grinding between work parts in a respective motion to one another. With the growth of sidelong drive known as upset to plastically diminish and merge the fabrics.

Because no dissolving happens, grinding welding is not a fusion welding method, but a solid-state welding strategy more like forge welding. FRW has utilization with metals and thermoplastics in a wide assortment of flying and car applications. Friction welding is helpful to work on wood.

Forge welding

Forge welding abbreviated as FOW could be a rigid state binding strategy that links two parts of fabric by warming them to a sufficient temperature and after that pounding them at once. It may moreover comprise the warming and constraining the metals besides presses or other implies, making sufficient weight to occur plastic misshaping at the bind surfaces.

This method is the only strategy of linking fabrics and has utilization since the antiquated schedule. Forge welding is flexible and is capable of joining comparable and different metals. Transformation, manual forge-welding generally supplant, even though mechanize forge-welding may be a common fabricating handle.

What are the material parameters of diffusion welding?

Diffusion welding may be a rigid linking method permitting for entire cross-sectional welding. The status of a diffusion-link junction decide by three fundamental parameters which are time, and weight, as well as bonding temperature. The trouble fitting the method is that they have interconnection in a nonlinear way.

Is cold welding real?

Yes, Cold welding also known as contact welding could be a solid-state welding strategy in which joining occurs without combination or warming at the interface of both parts that are going to be weld. Not at all like within the fusion welding forms, no fluid or liquid stage is display within the point.

How does explosive welding work?

Explosive welding varies from other conventional joining forms because it does not depend on the dissolving of metals that are joining. Also, it is not like cold or hot pressure welding in which plastic distortion occurs.

In straightforward terms an explosive weld got accomplish by including the cladding plate opposite to the substrate plate fabric utilizing the significant vitality from a hazardous release, coming about in a tall vitality rate effect.

What is the friction welding process?

Friction welding abbreviated as FRW could be a solid-state welding strategy that creates warmth via automatic grinding between work parts in a respective motion to one another. With the growth of sidelong drive known as upset to plastically diminish and merge the fabrics.

In what cases is the soldering of an aluminum surface using a torch?

One of the economical and practical problems is aluminum brazing in vacuum with a torch. This process becomes necessary in the event of shallow cracks in different microsystems, to eliminate all kinds of leaks.

The burner in these cases becomes an irreplaceable device that is helpful to use in ventilation and air conditioning systems. In this case, only aluminum brazing can save the situation.

Torch for brazing aluminum

So, you can carry out the use of a torch for brazing aluminum with the help of additional materials, such as tin, copper, and other flexible metals. Further, in their chemical composition, they are similar to aluminum and you can also solder with them.

Basic instruction applied in the aluminum soldering process

To carry out the soldering of aluminum, you can use equipment. It is portable and accessible to every person who is forced to use it in the process of malfunctions. The torches that are useful to use in this case become more practical than bulky welding machines. It also requires a constant connection to the electricity.

The process of aluminum brazing

First of all, in this case, in the process of soldering aluminum brazing in vacuum, you should pay attention to the following nuances and take them into account in your work:

You should prepare strong fire-retardant clothing, special devices that must be worn during work;

using degreasing agents and sandpaper of a certain size, you should clean the aluminum surface from dirt, dust, oil, paint, or other substances that can interfere in work in any way;

How to prepare aluminum brazing in vacuum?

It is necessary to clamp the repaired aluminum surface with some strong clamping device to securely fix the material.

In order to speed up the soldering process, it is necessary to apply an acid solution along the drawn line of breakage or rupture.

 

Then, in the process of work, the aluminum section should be heated with the help of a gas torch necessary for brazing until an orange color appears. This happens in the case of maximum heating of aluminum and reaching its limiting soldering point;

How to ensure effective process?

There is a need to use a solution of silver, vitriol and silumin for effective processing and securing the seam of an aluminum product. Using a gas torch, you can actively control the soldering itself with a different kind

aluminum brazing in vacuum close in physical properties;

Stopping the heating process, it is worth noting that further, it is necessary to water the defective area with boiled water;

The next step is to clean up remaining residues with a wire brush or sandpaper. Then the fixer should be applied to the defective area of ​​aluminum.

All of the above points, at which a full range of procedures carries out in the process of aluminum brazing in vacuum with a torch, are important components of an important troubleshooting process on this soft material. This is a necessary set of recommendations that we need to take into account in the process of work.

What are the advantages of using aluminum brazing in vacuum?

There are a lot of pluses and I find this use case for repairs suitable for some problems.

• Practically you need no additional equipment, except for a gas tank
• Mobility
• The possibility of soldering magnesium alloys with a content of the latter more than 3%.
• Ability to "solder" aluminum with copper.

Hardness/strength of the composition after cooling, generally higher than that of the base metal

• Cheapness of repair.

The cons are not so significant.

Although it is written that it is not harmful but I would not advise touching the rods with bare hands. (there is still chemistry that corrodes the aluminum oxide film)

To repair large parts, it is necessary to almost completely heat the entire part. I think it is not suitable for relatively high operating temperatures for aluminum (the melting temperature of aluminum is about 600g, the bar is 300-350)

 

In practice, everything is almost as simple as in the training videos. The only difference that parts such as honeycomb radiators can create problems to repair, due to insufficient "visibility" of the soldering point.

First of all, you need to clean everything mechanically and degrease. Then heat the part to that temperature until touching with the bar begins to "leave traces" of the liquid bar. I do NOT recommend directing the burner flame directly to the bar for aluminum brazing in vacuum.

The principle of the soldering iron

Soldering is especially popular in the assembly of various electrical and radio engineering devices.

Thanks to it, an electrically conductive connection of copper wires and other copper products with each other or with components of electrical circuits has been provided. Similarly, the soldering of elements made of aluminum and copper alloys.

When working with a soldering iron, the following occurs: from the moment when you connect the tool to the mains, the nichrome spiral begins to transmit electric current. Due to which it heats up. It transfers heat to the sting (rod), the heating temperature of which can increase up to 300 degrees.

To start soldering, you need a special substance - solder. Its melting point is lower so that the solder melts under the influence of the warm rod and provides the mandatory connection.

Soldering iron power and components for aluminum brazing work

First of all, you will need to purchase the tool itself. Today there are many varieties of soldering irons, they can differ in power, and also have different types of heating elements.

In cases where you need to solder large elements or wires with a large cross-section, you will need devices with a large rod, the power of which is about 100 watts. The power of soldering irons is available in the range of 50-80 watts.

It has specially designed to work with electrical and radio equipment. But for soldering small elements, a low-power tool with a thin rod is beneficial to use for aluminum brazing in vacuum.

Soldering aluminum for sensitive microcircuits

The lowest power rating of a soldering iron is in the range of 3-10 watts - such models are created specifically for soldering the most sensitive microcircuits.

In addition to the main tool, for proper soldering you will need:

Special stand

An accessory that is designed to securely fix the soldering iron.

Solder

In this alloy, as a rule, substances are essential to use: tin, lead, cadmium. Or any other metal with a suitable melting point.

Flux

A special substance that helps the adhesion (adhesion) of the solder by removing oxide and degreasing.

Additional tools

For more convenient and safe work with a soldering iron, you will need auxiliary tools:

Nippers

 They are necessary for cutting off the wire, stripping insulation, maintaining the part in the process.

File

Useful for cleaning the heated part of the tool.

Scalpel

It will be useful in the process of cleaning the treated surface.

Tweezers

It will help you not to burn yourself while working with very small parts.

Basic rules for soldering aluminum brazing in vacuum

You need to start with the correct preparation for soldering aluminum brazing in vacuum. The cleanliness of the object you are going to work with determines how quickly and efficiently you cope with the task, so first you will need to prepare the surface of the object with which you are going to work.

It must be free of grease, paintwork, or insulation residues. If you find them, the surface will need to be gently scrubbed with a scalpel and wiped off so that no dust remains.

Why it is good to use rosin fluxes?

In the process of soldering, it is better to use alcohol-rosin fluxes, as well as POS-61, POS-50, POS-40 solders. The flux must be applied immediately before the soldering itself when you complete all the preparations of the parts, otherwise, it may evaporate.

Next, you need to warm up the junction - to such a temperature that the solder attached to it can melt. With the help of solder, you gently solder the elements in the right place. This is a relatively straightforward process, the accuracy of which occurs with experience.

Rules to remember while working with a soldering iron:

1. The spike should be fast.
2. If the soldering of the wires did not work out the first time, let them cool down. Then you can try again.
3. Apply the tip of the tip as tightly as possible for the most effective process.

Good adhesion is usually shiny in aluminum brazing in vacuum. It was applied in a thin, even layer, without any cracks. Thanks to her, the device will last as long as possible, taking into account that nothing else in the device will break.

What is extrusion?

Anti-UV extrusion is a thermo mechanical transformation process in which a metal billet reduces in its cross section. When forced to flow through the hole of a die (tool), under the effect of high pressures and temperature. Like toothpaste being expelled from its tube.

The range of profiles that can be extruded from aluminum is virtually unlimited. The process reduces costs, as it eliminates subsequent machining or joining operations. Moreover, it makes it possible to obtain more resistant sections through the proper elimination of fragile joints and a better distribution of metal.

Among the main types of extruded products are solid, tubular and semi-tubular profiles. Its applications are ideal for the civil construction, consumer goods, electrical industry and transport sectors.

Drawing in anti-UV extrusion

It is a transformation process by cold mechanical deformation that allows the reduction of the cross section of a product. Analogous to lamination, the process increases the mechanical properties of the alloy.

Similarly, anti-UV extrusion also includes decreasing dimensional tolerances. Hence, it improves the surface finish and producing gauges that would be more complex to obtain by extrusion. Normally, non-treatable alloys and heat-treatable alloys (in which the function is dimensional accuracy) are there. The industry uses two wire drawing systems:

• In banks: for bars and tubes of larger diameter;
• In rotating blocks: for smaller dimensions of rebars and tubes.

Production processes

• Lamination
• Stamping
• Forging
• Foundry
• Welding
• Machining
• Finishes
• Recycling

When using aluminum in the construction of parts we are combining several advantages in one material. In addition to its beauty, aluminum provides durability and a low corrosion rate.

Although it has wide use worldwide, there is no single way to work with aluminum. Here at Alumax we work with aluminum extrusion.

What is Aluminum Extrusion?

Extrusion is a process where the aluminum billet undergoes thermo mechanical transformation. It happens through the action of heat and mechanical compression energies. When it flows through the hole of a matrix, also called tool. We can draw an analogy with the toothpaste that expels from the tube. At the end of the process we have an aluminum profile.

What is aluminum anti-UV extrusion for?

The aluminum anti-UV extrusion serves to manufacture profiles, with homogeneous cross section, to be used in the manufacture of various other aluminum products.

A widely used application is in the manufacture of bathroom shower profiles.

At the end of the process, the profile has a constant cross-section and length so, for companies that buy profiles. It becomes easier to work with this standardized material and thus gain scalability in their production stage.

Variety of extruded profiles

Each matrix, or tool, allows you to create a different profile. As we mentioned above, the most used profiles are for making the so-called kit's box. But we can have profiles for windows, stairs, electric bus bars and other infinity of profiles.

For example, if you work in the photovoltaic industry, your demand is for profiles that gear to your industry. So, each type of industry will need a different profile.

Alumax works according to the demand of its customers and offers a wide variety of profiles in its catalog. You can access by clicking here and get to know our tools.

Anti-UV extrusion manufacturers also have the convenience of creating the tool you need, depending on some factors. Get in touch with our sales team and ask all your questions.
Advantages of using an anti-UV extrusion extrude

1 - Storage

As the profiles are homogeneous, it is easier to plan the layout of your storage area and optimize the physical space of your factory.

2 - Price

Orders are in Kg and not in quantity of pieces. So, price when placing an order for extrude products tends to be lower than when purchase is in per unit.

3 - Use of billet

Related to the previous item, as everything fulfills in an automated way, the use of billet is very high. Which results in more pieces produced with the same amount of raw material?

4 - Physical capacities of the material

At the end of the extrusion process, the profile goes to an oven in order to improve its physical properties. Such as hardness and conductivity, so we have even more advantages added to aluminum.

Now that you know what an extrudate is, you know why to use an extrudate. And what are its advantages, you are now able to make the best decision for your industry.

ALUMINUM PROFILE ANTI UV EXTRUSION

The extrusion of Aluminum Profiles is a production process that allows producing pieces with a constant section, specifically a process by which through a plastic deformation, these parts with a constant section are available, for example plates, pipes, profiles and bars.

In industrial production, the extrusion process has use for metallic materials, such as aluminum, copper, lead or steel. The material to process and transform is usually in a pasty state, or in the form of pellets or powder, and has force by compression and into a shape in order to obtain the desired product, in practice an external form to be used.

Extrusion of plastic materials

If apart from obtaining the anti-UV extrusion process is hollow, the profile of the inner cavity is reproduced by a core which serves to derive precisely the desired section. If you have to do the extrusion of plastic materials, you will have to use the Archimedes screw, which pushes the work material into the head which then allows the final product to come out.

This type of plastic material we insert in the form of powder or pellets and the heat caused by friction with the walls of the extruder determines the final result.

What advantages anti-UV extrusion brings?

Thanks to the extrusion process, the production of aluminum extrusions guarantees most of the applications of the material, in the construction and mechanical sectors. Due to its plastic characteristics, the material is prepares well for this industrial production process.

The application of the process is valid only on materials with plastic physical characteristics in order to guarantee the plastic deformation process underlying the principle.

The function of molding in extrusion

The modeling takes place by compression of the material through a matrix design ad hoc to give the shape to the material being processed. It is essential that the aluminum is in a melt or soft state for the passage of plastic formation to occur.

To be able to extrude the Aluminum Profiles, we must bring the raw material to the ideal temperature, so that the friction force is low to the ideal level to obtain the product. The extrusion process can use different technologies depending on whether the extrusion takes place through the direct method or through the reverse one.

Conclusion

Adoption of it more and more by people, aluminum extrusions represent the majority of semi-finished products, which obtain from aluminum production. Once the anti-UV extrusion aluminum gets through, it comes to the final process.

What is Aluminum Profile Extrusion?

We all live in the world of information, and these days it will be difficult to find someone who has not heard anything about anti-static extrusion. We roughly imagine this complex, cumbersome and multi-stage process, but the key points on which it builds often remain invisible to an ordinary person.

In everyday life, people actively use aluminum to create transport, pipes, cables, optical systems, but what precedes these elements of the environment familiar to our eyes? It will be about the technology of extrusion of aluminum profiles in general.

What is extrusion?

In simple words, extrusion is a technological process of forcing a viscous melt of aluminum through a forming hole (matrix). This process carries out using special installations - extruders.

There are also different types of extrusion:

Cold blue extrusion - mechanical changes in the material, through its smooth and consistent processing;

Warm extrusion - aluminum has heat treatment by heating from the inside;

Hot extrusion is a change in the structure of aluminum by processing at high temperatures and speeds, which affects its quality indicators.

Purposes and features of anti-static extrusion of aluminum profiles

The anti-static extrusion process carries out in order to obtain a product of the desired shape, with a given cross-section, while making aluminum more durable and durable.

To start the aluminum extrusion process, you need to prepare in advance drawings, calculations and estimates to meet the requirements for the quality and shape of the product.

Aluminum extrusion stages

Like every technological process, extrusion has its own key (main) stages:

Extrusion begins with design, since there is a relationship between the parameters of the part and the parameters of production, and the specified profile determines the design of the product;

The billet, as the main raw material for this process, is present in a special container of the extrusion press;

Further, under the influence of the press, the workpiece remains solid, although it softens somewhat in the heating furnace. Interestingly, the melting point of aluminum is as much as 660 Celsius;

Preparation of the matrix - it is clean and slightly warm up to improve the passage of aluminum;

This stage combines a variety of matrix shapes with a high production speed, specialists constantly maintain the temperature and monitor the process of aluminum passage;

Computer simulation of aluminum extrusion

Introduction

Modern computer programs for modeling aluminum anti-static extrusion are capable of effectively improving the quality of extruded aluminum profiles even at the design stage of extrusion dies. Computer modeling allows improving the quality of produced aluminum profiles according to the following indicators:

• dimensional accuracy and profile shape
• strength and appearance of welds
• grain microstructure of material
• mechanical properties of the material

For an ordinary user of such a model, it often remains a “black box”, the internal structure of which is unknown or incomprehensible. Below we will try to explain some of the properties of these models, as well as show their potential usefulness for the practice of manufacturing aluminum extrusions.

The extrusion manufacturing aluminum process

In the sixth stage of production, aluminum becomes very plastic, to some extent - it is like squeezing out sauce or cream, the harder the pressure on the closed edge, the more the material is squeezes out.

At this point, the extrusion process itself begins, the plunger presses on the aluminum in the container with a force of 100 to 15,000 tons, the aluminum enters the die and slowly squeezes through its holes, resulting in a profile;

The product cools down and stretching machines straighten and correct possible twists;

Sawing - the aluminum profile cuts using circular saws;

Then something amazing happens, aluminum goes through the aging process, in ovens heats to the desired temperature. So, under the influence of temperature, aluminum becomes strong, strong and wear-resistant.

Thus, we have materials that, as a result, people use to equip cities, enterprises, design transport and much more.

Anti-static extrusion of aluminum profiles

The concept of anti-static extrusion profile is audible only in limited circles of specialists. And this is not surprising, since extrusion means a complex technological process, which consists of many technological operations.

The process itself consists in extruding material (aluminum) from a closed system through a special hole in the matrix, identical to the section of the extruded profile. All this has function in order to increase the service life of aluminum, to make it stronger, more durable and durable.

In turn, the pressing process usually consists of:

Preparation of pressing equipment;

Preparation of the technological system, as well as tools: matrix holders, press washers, dies, support rings, pads, knives for removing the pressure switch;

1. Pre-heating of the pressing tool
2. It is also necessary to heat the ingots in a gas oven
3. The next stage of extrusion of an aluminum profile is
4. Direct extrusion of the aluminum profile
5. Editing the profile on the stretching mechanism
6. Cutting the material to the measured length
7. Unfolding profiles into special baskets
8. Transportation and transfer of the profile to the aging oven
9. And the last stage is aging of the extruded aluminum alloy profile.

What is the role of these 9 stages in anti-static extrusion?

As a rule, the first anti-static extrusion stage does not require much time and is considered preparatory, but the second begins the most basic thing - pressing the profiles. The structures that are manufactured on the lines are launched in batches.

The mass of one batch is determined by the amount of finished products and the state of the matrix. The sequence of extrusion of profiles from aluminum alloy is regulated taking into account in order to avoid frequent alternation of alloys.

The first part that comes out of the press is usually the smallest and performs the following functions:

• Fills the channels of the matrix set;
• Responsible for the exit of the profile to the hot saw;
• Stabilizes the temperature of the pressing tools

The second part that comes out of the press stabilizes the size of the remaining parts. After that, the equipment is considered adjusted and the profiles are fully pressed and hardened.

And the last aging procedure is performed in the form of heat treatment of the alloy, which is quenched. This anti-static extrusion process consists in heating and holding the material at a high temperature.

Artificial aging in aluminum extrusion

After which the same material is cooled in air, which is called artificial aging. It is such an aluminum profile, which, even without being born - has aged. And can last more than a hundred years. And at the same time preserve any structure, from facades and window profiles to baguette and LED profiles.

How does custom profile extrusion work?

Basically, manufacturers need a lot of necessary equipment with some very special profile extrusion. Because it is very essential to complete the extrusion process with high accuracy.

Further, for better understanding, we have divided the whole process in 3 stages. It will actually help you to deeply understand that, how does custom profile extrusion work? So, these helpful stages are,

Stage # 1:

In the first stage, manufacturers feed the raw material, like, pellet or powder inside the machine extruder.

Stage # 2:

In this extruder, the material constantly conveys to the forward direction from the rotating screw. This rotating screw has placed into the heating barrel which keeps the material soft by heat and friction.

Stage # 3

In the next step, this molten metal reaches in the die, where it gets the specific shape. Further, die throw it in the cool water which helps to solidify the product.

Stage # 4:

At this point, it straight conveys to the rollers. Because this roller pulls all the soft and extra plastic from the die. Basically, die is a special kind of metal plate and has placed at the end of extruder along with the section. In this section cut, the product gets its final cross-section with the help of rollers.

Kinds of process manufacturers perform in custom profile extrusion

The situation is more complicated with those who do not know what exactly will be printed or with those who want to experiment with different materials and models. But more on that below.

Most modern models of 3D printers already have many functions. Such as Wi-Fi, Ethernet, a color displays with a touchscreen, a webcam for remote control of the printing process. It is partial or fully automatic platform calibration and others.

These extrude with two colors features can be very useful, but it is important to understand that their presence or absence does not directly affect print quality. Quality primarily depends on the design of the printer in general. And the extruder in particular, as well as many other mechanical and electronic components.

Two color plastic extrusion

At the moment, all plastics can be conditionally divided into 2 groups. These are ABS plastics, which include, in addition to ABS itself, Nylon, PC, HIPS, PC-ABS and others. PLA plastics include PVA, PET, PETG, Wood, Flex, TPE, TPU and others.

The decisive factor for choosing a printer may be the plastic you plan to print with. Because these two groups of plastics have different properties and, above all, different printing nuances.

A completely enclosed working chamber and a heated table are essential for printing with ABS plastic. As, for example, in the FlashForge Dreamer or UP BOX + 3D printer model. With these printers, you have the ability not only to set the site temperature. But also to maintain a high temperature throughout the entire working chamber, up to 90 ℃. Under these conditions, the risk of extrude with two colors model delamination during printing reduces and quality of finished model will be higher.

What is PLA two color printing?

A heated pad is optional for PLA printing. But good airflow of the model during printing is very important. Printing with PLA plastics is in many cases much easier for a beginner. An example of such printers is the MakerBot Replicator + or the budget Chinese models Wanhao Duplicator i3.

Choosing a 3D printer

An important characteristic of a 3D printer is the presence or absence of a heated table. Almost all 3D printer manufacturers claim that their products can be printed with all kinds of materials. But in practice this is not at all the case.

If printer does not have a heated bed, then printing any ABS plastics on it will be very difficult. Especially when you need to print large models.

Also, when choosing plastic for your tasks, you need to pay attention to the post-processing of models. Different materials have different properties not only during printing, but also in the form of finished products. For example, ABS plastic is easy to polish or gloss in an acetone bath, and PLA is good suitable for priming and subsequent painting.

Choosing a 3D printer

If you want to print with different types of materials, then you need a versatile extrude with two colors 3D printer that can handle any task. Such models also exist, for example Raise3D N1 Dual or FlashForge Creator Pro. The printer comes with a fully enclosed chamber, which is essential for ABS printing, but with a few easy strokes, you can transform it into a fully open state, perfect for PLA.

Printing with special plastic is a double experiment. For most 3D printers, manufacturers do not provide information on the possibility of printing with one or another type of experimental plastic.

Pay attention to the melting point of the plastic you are going to print with. It is also important to understand at what speed you need to print, taking into account the flow rate of this type of plastic.

It is also worth paying attention to such parameters as the size of the working chamber and the minimum layer thickness.

What is the price factor of two color extrude printer?

The larger the size of the working chamber, the higher the price, so it is worth deciding whether you need a large sized camera or whether a medium or small size camera is suitable for your needs. You also need to understand that printing large models will take a very long time, in some cases up to two days.

It may be better to print the model in chunks and glue it from the printed chunks of medium size.

Before that, I have made and tested a double swinging extruder. I also used the 'Y' extruder earlier. As you know, each of these extruders has its own pros and cons. As a rule, extrude with two colors extruders have a large consumption of plastic and time, and the "rocker" - the loss of printed volume.

Then I thought about combining these two types into one, or rather their positive aspects. This is how the revolver extruder was born.

The Uniqueness of extrude with two colors printer

Extrude with two colors uniqueness is that it allows you to print with two plastics from different nozzles, but the nozzles are positioned after switching at one point and the printed volume is not lost. Also, the unused nozzle rises, which eliminates the touching of the model.

In this type of extruder, it turned out to achieve better repeatability compared to the same "rocker". It is easier to service it, for its seemingly large dimensions, it actually takes up less space. The locking system invented by me excludes false switching, everything is securely locked.

Conclusion

This prototype still lacks shutters to cover an unused nozzle, but it is quite suitable for printing in this state. There are still a few mechanic modifications to come and more printing tests.

Most Popular Plastic Recycling methods

There are many technologies and equipment for the manufacture of products from various types of polymer materials. Plastic extrude process is one of the most popular plastic recycling methods.

Of course, not only plastic products come into existence with the help of extrusion. But in this article we will describe exactly the features of the processing of polymeric materials.

The extrusion method produces a huge variety of different products from polymers. Plastic pipes, pvc and composite profiles, plastic threads, windows, doors, polymer films and other products. The great popularity of extrusion is due to the high economy and productivity due to the continuous production process.

What is plastic extrude process?

An extruder of polymers is the equipment for the production of products by extrusion of polymer raw materials. The most common types of plastic extrude process machine designs are piston and screw (worm) type extruders.

Let's take an example of the design of a single-screw extruder. Raw materials load into the loading area through a cone-shaped container for loading raw materials. Typically, the polymer raw material for the extruder is a granular bulk material.

By means of a screw, the polymer granules move to the area of ​​the cylindrical body of the extruder. The auger rotates due to the operation of the electric motor through the gearbox.

How do we divide plastic extrusion process?

We can divide the extruder body into 3 zones. The area where the polymer load and not yet melt is called the loading area. And when it heats up, the melting zone begins. The third zone is the forming zone, when the molten polymer extrudes through the forming head and takes the desired shape.

The extruder barrel heats by heaters, which are present outside and tightly cover the entire surface. As electric heaters for the extruder, industrial heaters of the annular type are used or flat. If the extruder barrel is square, but still more often annular are of use.

Also, in each of the zones of the extruder barrel, cooling fans are of use in the design in order to remove excess heat from the heaters. Alternatively, you can use a special type of ring heaters - cooled clamp heaters.

Let's take a closer look at what types of ring heaters have use on plastic extrude process. And what are their main differences and features.

Ring heaters for extruder: plastic extrude process

Sleeve ring heaters are ideal for extruders as they are cylindrical in shape. And can fit snugly against the barrel surface in the heating zone. Clamp heating elements come with both in the form of a full ring with a coupler. And in the form of half rings or segments.

Ring heaters can consist of ceramic or micanite insulation, with various mounts, types of current leads, additional insulation or cooling elements and other features.

All resistive ring heaters use a high electrical resistance nichrome wire as a heating element, which heats up when an electric current passes through it. Let's consider the features of each type of ring heaters.

Cup mikanite heaters

Micanite in this type of heating element has use as an insulator between the heating coil and the outer casing during plastic extrude process. The heater body consists of stainless steel and in the case of micanite insulation. It can have a very large number of different cutouts, holes and connection types.

The maximum power of such heaters is up to 4 W per cm2, and the heating temperature is up to 350 degrees Celsius.

Nozzle heaters: plastic extrude process

It is also possible to manufacture micanite ring heaters with double heating coils. Thus a small heater with high power comes to expression. This type of ring heater has name nozzle heater because it has a use primarily to heat the nozzles of extruders.

Nozzle ring heaters can also be manufactured with a brass body that will be completely sealed without the fear of molten materials go into the body.

Ceramic clamp heaters

Heating elements with ceramic insulation will have a higher power (up to 9 W / cm2) and an operating temperature of up to 70C. Ceramic insulators made of steatite ceramics have high temperature resistance and insulating properties.

Ceramic ring heaters can also take place with an additional insulated jacket via plastic extrude process. Thus reducing their energy consumption by 25%. It will significantly reduce your electricity costs.

Ring heaters with cooling extrude process

With this design of heaters, both micanite and ceramic ring heating elements can be important. But in addition, a metal casing is common of stainless steel and a fan connects for blowing.

The design of the ventilated ring heater allows not only to obtain the most uniform heating, but also to quickly cool the extruder barrel if necessary.

Ring aluminum cast heaters

Cast heaters consist of a tubular electric heater, which has filling of aluminum in the form of half rings or rings. For aluminum heaters, an additional liquid cooling system is there, which can cool the heater in a short time.

Which type of ring heater is best for your type of extruder?

What characteristics are important? And other questions you can ask in the form of a question or just write us an e-mail, we will try to answer all your questions about heaters for extruders.

Production of various types of polymer products on plastic extrude process is also possible.

A wide variety of types of plastic products can be produced depending on the different openings on the die. The circular shape of the head allows the production of rods, cylindrical - plastic pipes and films, flat slotted. Films and profiles, complex shapes of extruder head are also possible in manufacture of window profiles and other products.

Production of plastic films on an extruder: plastic extrude process

Film is one of the most basic types of products that are made on extruders. Several technologies can have use for the production of plastic film, some of which we will consider in detail.

Blown film production

When molding plastic, an extruder with an annular hole shape on the forming head is used. To expand the ring of molten plastic even more after being pushed through the head, an air stream is blown into the ring through the device. As a result, the plastic of the pipe is stretched into the sleeve.

The air inside the sleeve must be supplied cooled so that the film has a uniform wall thickness. Therefore, a cooler is used in the construction for cooling. After the sleeve is inflated, it will need to be folded and twisted. In this case, guides, air-removing rolls and a winding device (9) are used.

Film production by plastic extrude process onto rolls

The forming head of the extruder for this type of film production is a slit shape, which is very narrow in height and rather wide (about 1.5 m) in width. A thin film of molten polymer feeds to the water-cooled rolls and solidifies there very quickly.

Film production by extrusion with pouring into a water bath

Plastic extrude process into a water bath is another way to produce plastic sheeting. When applied, polymer films come with even better quality. In the design of this extruder, a slotted die guides the plastic film as it enters the liquid bath, where the film is instantly cooled and solidified.

Extrusion of plastic pipes

For the molding of plastic pipes, mainly single-screw or twin-screw extrusion machines with a special design of an annular die head are used.

A mandrel places inside the forming head for plastic pipes, which serves to supply compressed air into the pipe. Outside are additional ring heaters that melt the polymer as it passes through this area.

Features of the use of extruded and pressed polypropylene sheets

For the production of semi-finished sheet products of the main types of plastics for industrial use, two production technologies are common: pp extrusion and injection molding.

This article provides an overview of the differences in properties and areas of application of semi-finished polyolefins (mainly sheet polypropylene) obtained by these two methods.

Features of pp extrusion

Extrusion is a theoretically continuous process of extruding a molten mass of material through a die (which can be of various shapes and sizes). The mass is set in motion by rotating the screw in a cylindrical melting chamber, which together with the screw is called the melting unit. The diameter and ratio of diameter to length of the cylindrical melting chamber determines the performance of the extruder.

Pickling bath made of extruded polypropylene sheet

Pp extrusion method allows the production of sheets up to 4000 mm wide and up to 70 mm thick. And in large-scale production is a more economical and productive process than injection molding.

Features of injection molding
The process is the molding of an article by melting a polymer raw material in a mold under pressure. The process of heating the material in the mold and the growth of the working pressure continues even after the material completely melts. It goes until all the air removes from the mass.

An element of a dialysis machine made from a pressed polypropylene sheet by mechanical processing.

The duration of the production cycle (filling, heating under pressure and cooling) depends largely on the thickness of the sheet (plate) produced. And this relationship is not linear.

For example, it takes 30 minutes to produce a 10 mm sheet, and 15 hours to produce an 80 mm board.
Obviously, this process is discrete, and from the point of view of productivity it is inferior to extrusion. But it is indispensable if it is necessary to produce plates with a thickness of more than 70 mm.

Comparison of pp extrusion and injection molding

During the pp extrusion process, the polymer in its primary forms entering the melting unit. Due to the rotation of the screw, experiences significant shear forces, heats up and homogenizes. It then experiences significant tensile forces by being squeezed through the die and pulled through the roller system.

In this regard, in the material after polymerization, so-called, orientation stresses and their value is significantly higher in the direction of extrusion.

During injection molding, internal stresses also arise in the material. But orientational stresses are inherent only in the extrusion process.

Depending on the manufacturing process, the resulting products differ significantly in terms of operating parameters such as:

• Shrinkage
• dimensional stability and
• Isotropic properties.

In addition, some difference we can note in the values ​​of the indicators of mechanical properties. These differences come by the fact that during extrusion, polymer molecules in the melt stretch in one direction. And later, depending on the cooling rate, the formation of different forms of crystallization is possible.

How to avoid problems in pp extrusion?

Unlike pp extrusion sheets, pressed boards are essentially isotropic. And problems can only arise from uneven cooling that occurs during thick board production. In this regard, the cooling of the plates also occurs under pressure in order to avoid uneven cooling and the formation of voids in the thickness of the material.

Due to the isotropy of the properties and low shrinkage of plates obtained by the method of injection molding, they are used in cases where it is necessary to ensure the uniformity of properties. It should be in all directions of the plate, for example, during further machining.

On the other hand, the large shrinkage of the material, typical for extruded boards, is in demand during thermoforming. However, it is necessary to take into account the difference in the amount of material shrinkage along and across the resulting sheet. It is in order to avoid deformation of the formed product.

Why pp extrusion plastic products are good to use?

We've been using synthetic plastics for over a century, ever since Leo Bakeland first invented plastic. However, it looks like a century later a populist "war on plastic" is taking place. Below are 6 reasons why plastic is doing us more benefits than we think, and they are all backed up by research from the British Plastics Federation (BPF).

1. Lightweight - Lightweight plastic parts save around 3000 liters of fuel over the life of an average car . This not only saves our money, but also reduces the amount of natural resources used.
2. Durability - the service life of products increases significantly. For example, plastic pipes can last over 100 years.
3. Saving water - making a plastic bag requires 25 times less water than making a paper equivalent.
4. Increase the shelf life of products - thanks to plastic packaging, products are stored much longer, vacuum packaging increases the shelf life by 2-3 days. Using plastic in packaging can help reduce food waste in supermarkets by 20%.
5. Recyclable – we can recycle pp extrusion plastic, although at the moment this is not always technically or economically feasible. However, recycling one ton of plastic bottles saves 1.5 tonnes of carbon.

Because of their low cost, ease of use, and versatility, plastics are used in a wide variety of products, from paper clips to spacecraft.

Types of plastic

Plastic is one of the greatest inventions of the 20th century. Without him, we would not have been able to see many other inventions. We tried to briefly and clearly describe the different types of plastic. What they are intended for and where they are used. This article will be useful not only for those who are going to make repairs, but also for those who care about their health.

1. PET (PETE), polyethylene terephthalate.

The most commonly used type of plastic, it is cheap to manufacture. PET is used in the production of most plastic bottles for drinks, ketchup, vegetable oil, and packaging of cosmetic products. Fragile and elastic material. Excellent rigidity and impact resistance.

That is why manufacturers of consumer goods love it, since the packaging does not crack during transportation.

PP extrusion  has high temperature resistance and can withstand temperatures up to 150 degrees Celsius. It is less dense than polyethylene, but also more solid. The only significant drawback of polypropylene is its high sensitivity to ultraviolet radiation and oxygen. Oxygen sensitivity decreases with the introduction of stabilizers.

Polypropylene is good for:

• packaging materials
• films
• lamp holders
• carpets, thermal underwear and fleece clothing
• TV cases, fuse boxes, some auto parts and car bumpers
• inhalers, disposable syringes and
• other plastic medical equipment that requires sterilization.

It is highly flammable, forming droplets. Polypropylene burns with a light flame with a blue core, releasing a pungent paraffin odor.

VARIETIES OF PVC AND THEIR APPLICATION

In this part, we will touch on the features of the so-called sheet extrusion. For the extrusion of flat sheet products, temperature control, residence time and streamlined flow path are important factors. Sheet and pvc extrusion lines also include cooling and polishing rollers.

What is pvc extrusion?

A general overview of the extrusion tool was given by the experts covering twin strand extrusion, a cost effective tool, as well as flow and cooling simulation and melt homogenization. Profile shaping comes by passing the extrudate. It passes through a series of calibration dies that cool the material through contact with the metal walls of the calibrators.

The role of vacuum holes in pvc extrusion

Vacuum holes or grooves are good to use with water cooled walls to enhance and maintain the dimensions of the final product. Alternatively, for a pipe extrudate, the material sizes and then cooled with water by full immersion or spray.

The influence of different cooling media showed a direct relationship between the temperature profile during cooling and deformation.

Pvc extrusion is a particular problem for PVC extrusion because it creates unwanted build-ups during the extrusion process that coat the screws, die, calibrator and other mechanisms.

In addition, the extraction of compounds from the extruder is usually accompanied by additional reactions arising from the ingredients of the composition in combination with processing conditions.

What methods are common in extrusion?

Several analytical methods are common in the study of sheet rolling technology using a specially designed die and calibrator. Moreover, design is also important to form finished products.

In the next part, we will consider such a process for manufacturing PVC products as foam extrusion. And then consider another popular technology, which we know as "injection molding".

How not to be mistaken when choosing ready-made pvc extrusion plastic windows?

The choice of plastic windows is not as easy as it might seem at first glance. The principle of "like it or not like it" does not work here, because there are a number of aspects to consider in order not to be mistaken.

A reliable pvc extrusion manufacturer is not the only thing that should play a role in the selection. Finished PVC windows in stores may be of poor quality.

Replacing windows is one of the first stages of a major overhaul. And most often the choice of consumers falls on PVC structures. Ordinary wooden windows are also good in their own way. But the list of advantages of modern plastic windows is much wider.

So that replacing old windows with new ones or just purchasing new windows will bring you only positive emotions, it is important to choose a reliable manufacturing company, ensure high-quality installation of finished products and follow all the rules for their operation. What is so good about plastic windows? Let's name their main advantages.

Thermal insulation and energy saving with PVC extrusion

Windows made of PVC extrusion profiles have excellent thermal insulation properties, which are an order of magnitude higher than that of simple wooden windows, not to mention the usual, "cold" aluminum. Plastic does not conduct heat well, and structures made of it have high dimensional stability and ensure proper tightness.

Of course, not only the profile plays a very important role, but also the translucent filling - the glass unit. Useful bonuses in the form of low-emission glass with silver atoms and an inert gas (argon, krypton) inside the glass unit further reduce heat loss. The experience of using PVC windows shows that replacing old structures with them can reduce heating costs by about a third.

 

How not to make a mistake when choosing?

The window is not only glass. It consists of several parts, each of which affects the properties of the structure and is important. So that the window is really reliable and provides good heat and sound insulation,

Attention should be paid to three components of pvc extrusion profiles:

• glass unit,
• profile,
• fittings.

Installation is also important, since the service life and performance of functions depend on the correct installation of the window.

The profile must have sufficient rigidity; reinforced frames correspond to this indicator. Such frames will cope with a serious load. The number of profile chambers is also important, since the more there are, the better heat retention will be provided by the window.

Environmental indicators are also important, because compliance with quality certificates guarantees that the health of the tenant will not be in danger. For those buyers who care about external indicators, it is worth taking a closer look at the design.

The role of glass in profiles

A double-glazed pvc extrusion window is selected according to the indicators of the number of glasses and their type. The more glass there is, the better the window will perform its function of protecting against the cold from the sound from the street.

Optimally - a double-glazed window, but there are options with a large number. The type of glass is selected based on personal and climatic needs. The range includes incandescent and energy-saving double-glazed windows.

For fittings, you should focus on the strength of the parts and their durability. It is also necessary to ensure the functionality of the parts, otherwise the window will quickly become unusable, and its replacement will require an investment.

Pvc extrusion windows - colored or white?

Colored windows are no longer a gimmick. Customers are bolder in choosing painted or laminated profiles instead of standard white ones. We can select for any interior, and both textures and shades vary. However, colored plastic windows have disadvantages.

Choosing the color of the window

The classic white profiles are unpretentious and easy to clean. For them, manufacturers have developed a lot of cleaning and washing products, and the choice of accessories is wide. The situation with colored windows is more complicated.

Finding accessories for colored plastic windows is also more difficult. Unique pvc extrusion profile shades require matching handles, which are not always available in shops and manufacturers' websites.

Conclusion

This is where white windows win because it's easy to find standard fittings and accessories. If for the landlord there is no fundamental difference in the color scheme of the plastic profiles, then it is worth stopping at the white version. But those who want to create a unique style of the house will have to spend money.

Why it is important to choose ideal manufacturers of plastic extrusion?

The plastic extrusion process has become most popular in order to create fixed cross-sectional items in recent years. Its ideal products are cables, pipes, gaskets and several different objects which are extremely useful in different industries.

Which kind of operators does plastic extrusion manufacturers employ?

Extrusion operators are also known as drawing machine operators or extruding. They actually have to monitor and control machines which works to shape all kind of thermoplastic materials.

Plastic extrusion manufacturers mostly prefer to employ operators who have GED or high school diploma. But they always choose those operators who can perform best instead of their diploma. Moreover, they should have best working experience.

In fact, to get this job you don't need to any kind of formal education. Good and established companies always arrange some on-the-job training process. In this way, these companies actually train their trainees by giving them some basic and helpful tasks.

Which job activities plastic extrusion manufacturers assign to extrusion operators?

Mostly manufacturers at plastic extrusion gives several tasks to their operators during their jobs. So, good operator always has to perform these essential tasks because they are base for any big or complex production.

Activity # 1:

First of all, they mix thermoplastic materials with colored dyes which are in the form of powder or pellets.

Activity # 2:

After this mixing process, they feed this mixture to the extrusion machines.

Activity # 3:

In this step, these operators have to set the controllers and dials of the extruding machines to make sure that product will be in,

• exact size;
• thickness and shape.

Activity # 4:

When the products have created, these operators have to test and measure them to compare with their actual specifications.

So, plastic extrusion manufacturers generally assign all these important job activities to their operators. A good operator always performs them with highly accuracy because they are essential for his job.
