2023-04-25 08:45:10

Precision metal stamping parts are ubiquitous in our lives. There are many processes in the production of metal stamping parts, but the hardness of precision metal stamping parts is very important. How do we test it? Shenzhen Chengruifeng The editor of metal stamping will give you a brief introduction.

The processing of metal stamping parts includes punching, bending, deep drawing, forming, finishing and other processes. The materials for stamping parts processing are mainly hot-rolled or cold-rolled (mainly cold-rolled) metal strip materials, including alloy steel plates, carbon Steel plate, spring steel plate, galvanized plate, tinned plate, stainless steel plate, copper and copper alloy plate, aluminum and aluminum alloy plate, etc.


Automotive Stampings


Alloy stamping parts are commonly used parts in the field of metal processing and machinery manufacturing. Stamping parts processing is a processing method that uses molds to separate or form metal strips. The main purpose of the hardness test of metal stamping parts is to determine the purchased metal sheet. Whether the degree of annealing is suitable for the stamping parts to be processed later, different types of stamping parts processing require plates with different hardness levels.

The aluminum alloy plate used for stamping processing can be tested with a Webster hardness tester. When the material thickness is greater than 13mm, a Barcol hardness tester can be used instead. A pure aluminum plate or a low-hardness aluminum alloy plate should use a Barcol hardness tester.
