The hardness test of metal stamping parts is carried out using a Rockwell hardness tester. Small-sized and complex-shaped stamping parts can be used to test those with very small flat surfaces that cannot be detected on ordinary bench Rockwell hardness testers.

Stamping parts processing includes processes such as blanking, bending, drawing, forming and finishing. The materials for stamping parts processing are mainly hot-rolled or cold-rolled (with cold-rolled being the main type) metal sheet and strip materials, such as carbon steel sheets, alloy steel sheets, spring steel sheets, galvanized sheets, tin-plated sheets, stainless steel sheets, copper and copper alloy sheets, aluminum and aluminum alloy sheets, etc.

The PHP series portable surface Rockwell hardness tester is highly suitable for testing the hardness of these stamped parts. Alloy stamping parts are the most commonly used components in the fields of metal processing and mechanical manufacturing. Stamping parts processing is a processing method that uses molds to separate or shape metal sheets and strips. Its application scope is extremely wide.

The hardness testing of stamping parts materials is mainly aimed at determining whether the annealing degree of the purchased metal sheets is suitable for the subsequent stamping processing. Different types of stamping processing techniques require sheets of different hardness grades. Aluminum alloy plates used for stamping parts processing can be tested with a Vickers hardness tester. When the material thickness is greater than 13mm, a Brinell hardness tester can be used instead. Pure aluminum plates or low-hardness aluminum alloy plates should be tested with a Brinell hardness tester.

In the stamping parts industry, as introduced by Chuangxing Hardware Products Factory, stamping is sometimes also called sheet metal forming, but there is a slight difference. Sheet metal forming refers to the forming methods that use sheet metal, thin-walled tubes, thin profiles, etc. as raw materials for plastic processing. At this time, the deformation in the thick plate direction is generally not emphasized.
