• Marine;
• Lighting;
• Refrigeration;
• Construction;
• Power management;
• Recreational vehicles;
• Upholstery and furniture and many more.

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

In fact, there are many other valuable processes which a good custom service performs during the custom profile extrusion.

So, we are here to give you helpful information about these extrusion processes.

Cross Heading:

Actually, this process is extremely helpful to perform custom operations in order to get some individual needs.

Embossing:

This is a very unique and particular process. Because it helps to upraise the final texture of your custom designs. Actually, it can create some very special designs on your plastic extrusion.

Tri-Extrusion and Dual-Durometer:

This process is very helpful to add several materials in your single extrusion process.

Capstock:

Generally, it is very special kind of resin. Because it can help to protect anything from windows and decks to golf carts and pools.

Miter Cutting:

Basically, a miter cut is a particular type of angled cut on the top of two structures. Moreover, it allows joining together and makes a miter joint or corner.

Tips which your custom profile extrusion service must follow

Here are some helpful tips that your custom profile extrusion service should follow to avoid several problems. Furthermore, they can also get good results to apply these useful tips.

These are:

Tip # 1: Regulate feed throat temperature:

Always regulate feed throat temperature because it improves the processing of solid materials.

Tip # 2: maintain a stable regrind form:

It is very important to maintain the consistent shape because it helps to promote mass density.

Moreover, it also improves the flow in feed hopper. There are many profile extrusion services; the most important thing is too how to choose a reliable company for your next extrusion process? You need a professional extrusion company with contemporary tools and skills.

Two-color printing made easy

To choose extrude with two colors 3D printer that is right for you, you first need to decide what you will print. This will determine which 3D printer model is best for you for these purposes.

It is important to understand that desktop 3D printer is not a machine for production of mass production of products. It is a tool for creating models, prototypes, design or printing small batches of small parts.

A 3D printer cannot completely replace a thermoplastic machine, silicone molding or a CNC milling machine. But at the same time it can become an indispensable tool for creating a high-quality prototype or demonstration model. A 3D printer is a great hobby that can even generate income for you.

2. If you already know what you will be printing, you need to determine which plastic is best for printing the models you need.

Choosing a extrude with two colors 3D printer

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.

ABS product after extrude with two colors bath

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. Moreover, plastic extrusion manufacturers are increasingly providing all these beneficial objects in all over the world.

In fact, in the extrusion process, manufacturers are using several other materials. But plastic extrusion items have extreme worth because of their,

• durability;
• strength;
• low cost;
• usability and many more.

For getting best plastic production which have all the above qualities, selecting good manufacturing services is very important. So, we are here to tell you how you should pay attention while choosing the best manufacturers.

This guide will also help you to know about best polymers which plastic extrusion manufacturers use to get ideal productions. You will also get all other important information about plastic extrusion and its manufacturers.

What is plastic extrusion? plastic extrusion manufacturers

Basically, plastic extrusion is a very high-volume manufacturing process. In this extrusion process, manufacturers melt the raw plastic and form it into a continuous profile. In plastic extrusion, they can actually produce several kinds of items which are essential to use in many industries.

Further, these items are also immensely helpful to use in residential as well as in commercial needs. It is greatly beneficial to create items of any length such as, pipes. But it depends on the flexibility of the materials which plastic extrusion manufacturers use in plastic extrusion.

In fact, there are several types of plastic extrusion which are suitable to create different objects. Good manufacturers always know how to make use of each of them for producing their specific particles. These useful types of plastic extrusion are:

Famous types of plastic extrusion and their uses:

Furthermore, just like several other industries, there are also plenty of options to finish your aluminum extrusions. For example, powder coating.

Basically, you also have other helpful options for high quality aluminum finishing. The other options are also very popular and useful such as, anodizing and painting. All of these choices have several unique benefits and they are also suitable according to some specific conditions.

What is the role of better finish in powder coating?

These finishes can provide you best protection against corrosion and many more. As well as they also have ability to provide you ideal aesthetic appeal. But here we will discuss about powder aluminum coating. What does it mean and how it is advantageous for your aluminum extrusions?

Moreover, you can also get some important steps to prepare aluminum for powder coating. How you can do it at home and some problems while coating aluminum by powder?

What does powder coating mean?

The powder aluminum coating means that you coat your metal workpiece with a special powder. Nowadays it has become a very popular process to secure your aluminum parts and components. In this process, you can add finishing to your aluminum extrusion according to the needs of its medium.

Basically, by using this process you add a special paint on the surface of your aluminum extrusions. Moreover, this special paint comes in the form of powder. The object on which you have to apply this powder must be electrostatically charged.

Moreover, you have not to use any type of solvent for completing the powder aluminum coating. But before powder coating, for the best adhesion of the paint, you have to properly treat the whole surface. So that there should not be any kind of issue after the coating process.

Actually, this process of coating is only appropriate for all of your metal parts.

How to prepare aluminum for powder coating?

In fact, you do some pretreatments in other processes of finishing your metal pieces for better painting or anodizing results. Similarly, in this process of powder aluminum coating, you also have to do some vital treatments for better finishing solutions.

Furthermore, there are generally 6 initial processes to ideally prepare the aluminum for powder coating.

Such as,

• The surface cleaning;
• The solvent cleaning;
• Hand and power tool cleaning;
• Sweep blasting;
• Phosphate treatment;
• Aqueous Alkaline cleaning.

The surface cleaning:

At first you have to make sure that your aluminum parts are totally clean. For example, you have to make sure that all type of

• grease;
• dust;
• and several other particles;

have perfectly removed in order to do proper adhesion. Basically, the cleaner your aluminum part is, the better and more durable the powder aluminum coating layer will be.

The solvent cleaning:

In this process of cleaning the aluminum part, you have to clean by using conventional cleaning solvents. Generally, you can use,

• high-flash naphtha
• mineral spirits, etc.

Because they are best to remove grease and oil from the aluminum components for ideal results of powder coating. For perfect cleaning, you should always use appropriate brushes or rags to wipe parts perfectly.

Further, you should strictly clean these brushes or rags. Because remaining dirt or oil in these brushes have chances to transfer back to the aluminum part. You can clean all these parts with the help of ultrasonic baths of solvents.

And after this bath rinse them thoroughly in hot water. After rinsing, dry all these parts before the next process.

Hand and power tool cleaning:

You can also clean light deposits of aluminum by using power tool and hands.

Sweep blasting:

The brush blasting or abrasive sweep actually uses the movement of rapid nozzle. Moreover, this rapid movement has ability to roughen the aluminum surface. Hence, it can make the aluminum part ready for powder coating.

Phosphate treatment:

In this process, you actually convert the aluminum surface to a crystalline phosphate coating of proper texture. This process has done to inhibit corrosion for durability and adherence of the powder aluminum coating.

You can apply this process with the help of spray, soft bristle brush application or with the help of immersion. Moreover, after 3 to 6 minutes, you should wash the whole surface with simple clean water. Leave it for a while to dry it completely before applying the powder aluminum coating.

Aqueous Alkaline cleaning:

Actually, the solution of alkaline contains 2 to 5 % sodium compounds. Further, it also has a very small addition of,

• chelating;
• emulsifying;
• sequestering agent or may be combination.

You can easily apply this solution by using spray machines or with the help of brushes. If you want its best results, you should keep it in the temperature of 60°C to 85°C. Basically, this temperature is ideal for this process of preparing aluminum for powder coating.

So, after cleaning with the solvent of Alkaline, you have to wash the aluminum part deeply by hot water. Let dry it properly. But for better results, you should use heated drying in order to best removal of water.

Hence, all the above methods are necessary to prepare aluminum components for aluminum powder coating.

What is the powder coating process?

The whole process of coating the powder to your aluminum extrusions is as follow;

1^st step:

As we have already described that before starting the process of powder aluminum coating, you have to pretreat aluminum surface. It is essential part of this coating process. Because it helps to ensure the ideal adhesion. Further, the powder coat will not flake and it will be extra durable.

2^nd step:

In this step, your selected technician will spray the powder with the help of electrostatic spray gun. But for accurate powder coating, first the technician has to make sure that aluminum part must have the positive charge. Actually, this positive charge helps to make the powder bond with the extrusion of electrically-grounded.

3^rd step:

In the 3^rd step, your technician will put the aluminum extrusion inside the big curing oven. This oven actually will bake the aluminum component till you get a uniformly-melted coating.

4^th and final step:

In this final step, the technician removes the baking extrusion in order to cool it completely. So, after cooling the aluminum part, you can easily get a very smooth and hardened powder coating.

What are powder coating aluminum problems?

As this latest powder aluminum powder method has lots of benefits, like,

• It has ability to give you lots of charming and bright colors options;
• More reliable and environment-friendly than anodizing or liquid paint;

But this method of coating also can create some problems for your aluminum extrusions.

Generally, there are 5 most common problems which can create problems for you. Moreover, you will have to face all these general issues, if you use polyester powder coat. These 5 common problems are:

1. Skinny Corrosion
2. Inclusions or orange peel
3. Chalking
4. Failure of the aluminum coating in order to adhere
5. Unstable color match.

Does powder coating weaken aluminum?

When you are making your aluminum extrusions safe by using powder aluminum coating, you may think,

• is it safe for your aluminum parts?
• can powder coating weaken your aluminum components?

So, we are here to explain you. In fact, there is no harmful effects of this method to your aluminum or any other metal alloy. In this method, technicians actually use the curing temperature around 177 - 190 C (350 - 375 F). Hence, this temperature has no side effect on the metals.

Conclusion:

The powder coating process is highly advantageous in comparison to anodizing. Because it gives you a vast range of colors selection. Moreover, when we compare it to oil paint, we find it safer. Because, the waste powder is not hazardous like the wet paint.

Further, you can also collect this waste powder and can reuse it. So, this coating will be an ideal choice for you, if you want extra unique textures with some bright colors.
