For testing the thickness of large product of precision metal stamping parts, we would using rockwell hardness tester.
For Small products, stamping parts with complex shape, can be used to test the plane is small, can't test on ordinary desktop rockwell hardness tester.
The processing of precision metal stamping parts, it is including stamping, bending, stretch, forming and special finishing process. The main material of stamping parts is hot rolled or cold rolled (mainly cold-rolled), beryllium copper, copper and copper alloy, tensile SUS304, SUS301, stainless iron SUS430 and SUS409, pure aluminum and aluminum alloy, aluminized steel, galvanized sheet, tinplate, spring steel and other metal materials.
PHP series portable surface rockwell hardness tester is applicable to test the hardness of the stamping parts. Metal stamping parts is the most commonly used metal processing, machinery manufacturing parts.
The processing of stamping parts is completed by the following steps, Mould making - separation of metal materials by mould-forming by stamping. Its application range is very wide.
The testing of the raw material hardness of precision metal stamping parts, its main purpose is to determine the suitable for stamping of the material by annealing, Because of the stamping process is different, the hardness of raw material is different also. We could use wechsler hardness tester for aluminum alloy plate by stamping.
In the industry of metal stamping parts, sometimes called sheet forming, but slightly difference. As for sheet forming, it refers to use thin plate, thin wall pipe, thin material as raw materials, the method of plastic forming, which are collectively referred to as sheet metal forming.
