Hardness of metal stamping parts

The hardness test of Dongguan hardware stamping parts adopts Rockwell hardness tester. Small stamping parts with complex shapes can be used to test the surface is very small, can not be tested on the ordinary desktop Rockwell hardness tester.　　　　 Dongguan hardware stamping parts processing includes punching, bending, deep drawing, forming, finishing and other processes. The materials processed by Dongguan metal stamping parts are mainly hot-rolled or cold-rolled (mainly cold-rolled) metal sheet and strip materials, such as carbon steel plates, alloy steel plates, spring steel plates, galvanized plates, tin plates, stainless steel plates, copper and Copper alloy plates, aluminum and aluminum alloy plates, etc.　　　 PHP series portable surface Rockwell hardness tester is very suitable for testing the hardness of these stamping parts. Alloy stamping parts are the most commonly used parts in metal processing and mechanical manufacturing. Stamping processing is a processing method that uses molds to separate or shape metal strips. Its application range is very broad.　　　　The main purpose of the hardness test of stamping parts is to determine whether the annealing degree of the purchased metal sheet is suitable for the subsequent stamping parts processing. Different types of stamping parts 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, it can be changed to a Barcol hardness tester. The pure aluminum plate or low hardness aluminum alloy plate should use the Barcol hardness tester.　　　　 In the stamping industry, stamping is sometimes called sheet forming, but there is a slight difference. The so-called sheet forming refers to the forming method of plastic processing using sheet material, thin-walled pipe, thin profile, etc. as raw materials, which is collectively referred to as sheet forming. At this time, the deformation in the direction of the thick plate is generally not considered. Previous post: Description of metal stamping parts
