Hardware stamping parts inspection content
08-21 / 2019

Rockwell hardness tester is used for hardness testing of hardware stamping parts. For example, small stamping parts with complex shapes can be used to test flat surfaces that are too small to be tested on a regular desktop Rockwell hardness tester.


Stamping parts processing includes processes such as punching, bending, deep drawing, forming, and finishing. The materials used for stamping parts processing are mainly hot-rolled or cold-rolled (mainly cold-rolled) metal sheet and strip materials, such as carbon steel plate, alloy steel plate, spring steel plate, galvanized plate, tinplate, stainless steel plate, copper and copper alloy plate, aluminum and aluminum alloy plate, etc.


The PHP series portable surface Rockwell hardness tester is very suitable for testing the hardness of these stamped parts. Alloy stamping parts are the most commonly used parts in the fields of metal processing and mechanical manufacturing. Stamping processing is a processing method that uses molds to separate or form metal plates and strips. Its application range is very broad.


The main purpose of hardness testing for stamping materials is to determine whether the annealing degree of the purchased metal sheet is suitable for the subsequent stamping processing. Different types of stamping processing processes require different hardness levels of sheets. Aluminum alloy plates used for stamping parts processing can be tested using a Vickers hardness tester. When the material thickness is greater than 13mm, a Babbitt hardness tester can be used instead. Pure aluminum plates or low hardness aluminum alloy plates should use a Babbitt hardness tester.


In the stamping parts industry, stamping is sometimes also known as sheet metal forming, but there are slight differences. The so-called sheet metal forming refers to the forming method of plastic processing using sheet metal, thin-walled pipes, thin profiles, etc. as raw materials, which is collectively referred to as sheet metal forming. At this time, the deformation in the direction of the thick plate is generally not particularly considered
