Testing of metal stamping parts
Nov 01, 2018

The hardness test of metal stamping parts adopts Rockwell hardness tester.

Small, complex-shaped stampings can be used to test the plane very little and cannot be detected on a common benchtop Rockwell tester. Stamping parts processing including punching, bending, drawing, forming, finishing and other processes.

Stamping parts processing materials are mainly hot-rolled or cold-rolled (mainly cold-rolled) metal strip material, such as carbon steel plate, alloy steel plate, spring steel plate, galvanized plate, tinned plate, stainless steel plate, copper and copper alloy plate, aluminum and aluminum alloy plate. The PHP series of portable surface Rockwell hardness Testers are ideal for testing the hardness of these stamped parts. Alloy stamping parts are most commonly used in metal processing and mechanical manufacturing. Stamping parts processing is the use of molds to make the metal strip separation or forming process method.

Its application scope is very broad. Stamping parts of the hardness testing, the main purpose is to determine whether to buy the metal plate annealing degree is suitable for the subsequent stamping parts processing, different types of stamping parts processing technology, the need for different hardness level of the plate.

For stamping parts processing aluminum alloy plate can be detected by the Vickers hardness tester, the thickness of the material is greater than 13mm may be used to the bar hardness, pure aluminum or low-hardness aluminum alloy plate should be used in the bar hardness tester. In stamping parts industry, stamping is sometimes called sheet metal forming, but slightly different. The so-called plate forming refers to the sheet, thin-walled tubes, thin profiles, such as raw materials for plastic processing of the forming method referred to as sheet metal forming, at this time, the deformation of the thick plate direction is generally not focused on consideration.
