The hardness of metal stamping parts is measured by Rockwell hardness tester. Small, complex-shaped stampings can be used to test small planes that cannot be tested on ordinary benchtop Rockwell hardness testers.

The processing of stamping parts includes punching, bending, 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 sheets, alloy steel sheets, spring steel sheets, galvanized sheets, tin-plated sheets, stainless steel sheets, copper and copper alloys. Plate, aluminum and aluminum alloy plates, etc.

The PHP series of portable surface Rockwell hardness testers are ideal for testing the hardness of these stamped parts. Alloy stampings are the most commonly used parts in metal processing and machine building. Stamping processing is a processing method in which a metal strip is separated or formed by a mold. Its application range is very broad.

The hardness of the stamping material is mainly determined by determining whether the degree of annealing of the purchased sheet metal is suitable for the subsequent stamping process. Different types of stamping parts are required for different hardness grades. The aluminum alloy plate used for stamping processing can be tested by a Vickers hardness tester. When the material thickness is greater than 13 mm, the Barcol hardness tester can be used. The pure aluminum plate or the low hardness aluminum alloy plate should be a Barcol hardness tester.

In the stamping industry, stamping is sometimes referred to as sheet forming, but with a slight difference. The so-called sheet metal forming refers to the forming method of plastic working with a sheet material, a thin-walled tube, a thin profile or the like as a raw material, which is collectively referred to as sheet metal forming. At this time, the deformation in the direction of the thick plate is generally not considered.
