| Inspection of metal stamping parts The hardness of metal stamping parts is tested by rockwell hardness tester. Small stamping parts with complex shapes can be used to test that the plane is too small to be tested on a normal bench rockwell hardness tester. Stamping parts processing including blanking, bending, drawing, forming, finishing and other procedures. Stamping parts processing materials are mainly hot rolled or cold rolled (mainly cold rolled) metal strip materials, such as carbon steel, alloy steel, spring steel, galvanized plate, tinplate, stainless steel plate, copper and copper alloy plate, aluminum and aluminum alloy plate. The PHP series portable surface rockwell durometer is ideal for testing the hardness of these stamping parts. Alloy stamping parts are the most commonly used parts in metal processing and mechanical manufacturing. Stamping parts processing is the use of mold to make the metal strip separation or forming processing method. Its application range is very broad. The main purpose of the hardness test of stamping materials is to determine whether the annealing degree of the sheet metal purchased is suitable for the subsequent processing of stamping parts. The processing technology of different kinds of stamping parts requires plates of different hardness levels. The aluminum alloy plate used for stamping parts processing can be tested with a wechsler hardness tester. If the material thickness is greater than 13mm, the material thickness can be changed to a pap hardness tester. Pure aluminum plate or low-hardness aluminum alloy plate should be tested with a pap hardness tester. | ||||
