Metal stamping parts are widely used in various fields of our lives, including some electronic devices, auto parts, decorative materials and so on. The metal stamping parts we usually refer to generally refer to cold stamping parts. For example, if you want to turn an iron plate into a fast food plate, you must first design a set of molds. The working surface of the mold is the shape of the plate. , Press the iron plate with a mold, and it becomes the plate you want. This is cold stamping, which is to directly stamp the metal material with the mold.

The processing of metal stamping parts includes such processes as punching, bending, deep drawing, forming, and finishing. The materials processed by metal stamping parts 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, tin plate, 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 metal stamping parts. Alloy metal stamping parts are the most commonly used parts in the field of metal processing and mechanical manufacturing. Metal stamping parts 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 testing of metal stamping parts is to determine whether the annealing degree of the purchased metal sheet is suitable for the subsequent processing of metal stamping parts. Different types of metal stamping parts processing techniques require plates of different hardness levels. The aluminum alloy plate used for the processing of metal stamping parts can be tested with a Webster hardness tester. When the material thickness is greater than 13mm, the Barcol hardness tester can be used. The pure aluminum plate or the low hardness aluminum alloy plate should use the Barcol hardness tester. In the hardware stamping industry, stamping introduced by Shenzhen Chuangxing Hardware Products Factory 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, collectively referred to as sheet forming. At this time, the deformation in the direction of the thick plate is generally not considered.
