What is metal stamping

Rockwell hardness tester is used for hardness testing of metal stamping. Small, stamped parts with complex shapes can be used to test small planes and cannot be tested on ordinary desktop Rockwell hardness testers. PHP series portable surface Rockwell hardness tester is very suitable for testing the hardness of these stampings. Alloy stampings are the most commonly used parts in metal processing and machinery manufacturing. The stamping part processing is a processing method that uses a die to separate or shape the metal strip. Its application range is very broad.

metal Stamping parts processing includes blanking, bending, deep drawing, forming, finishing and other processes. The materials processed by stamping parts are mainly hot-rolled or cold-rolled (mainly cold-rolled) metal strip materials, such as carbon steel plates, alloy steel plates, spring steel plates, galvanized plates, tinned plates, stainless steel plates, copper and copper alloy Plate, aluminum and aluminum alloy plate, etc.

1. Hardness testing of stamping parts

The main purpose of hardness testing of stamping parts is to determine whether the annealing degree of the purchased metal sheet is suitable for the subsequent stamping part processing. Different types of stamping part processing techniques require plates of different hardness levels. The aluminum alloy plate used for stamping parts can be tested with a Webster hardness tester. When the thickness of the material is greater than 13mm, the Barcol hardness tester can be used. The pure aluminum plate or the low hardness aluminum alloy plate should use the Barcol hardness tester.

2. Hardness testing of stamping parts mold

The main material of the stamping die is die steel (including tool steel and high-speed steel), and sometimes carbide is used.

Stamping parts molds usually require high hardness and wear resistance, heat treatment is essential.
