Stampings, including metal stampings, metal stamping parts and so on, in general, is a major category, wide range of applications, stampings for hardness testing of materials, is also required, not just testing. Today we talk about one of them, that is, metal stampings, explain about its application and process knowledge.

Metal stamping parts used in electronic devices, auto parts, decorative materials, we usually say stampings generally refers cold stamping parts, is the direct mold stamping on metal materials.

Hardness testing of metal stamping parts Rockwell hardness, small, stamping parts with complex shapes can be used to test the plane is very small, can not be detected on a normal desktop Rockwell hardness.

Stamping parts processing, including punching, bending, deep drawing, forming, finishing and other processes. Materials stamping parts processing is mainly hot-rolled or cold-rolled (cold-rolled-based) metal strip material, such as steel plates, steel plates, spring steel, galvanized sheet, tin plate, stainless steel, copper and copper alloys plates, aluminum and aluminum panels.

Alloy metal stamping parts processing, machinery manufacturing the most commonly used parts, stamping parts processing is the use of mold forming the metal plate separation or processing methods with the occurrence, very broad range of applications.

Hardness testing stamping materials, its main purpose is to determine the extent of annealed sheet metal stamping parts purchased are suitable for subsequent processing to be carried out, different kinds of stamping process, require different levels of hardness plate. Aluminum alloy plate for stamping parts available Webster hardness testing, the material thickness greater than 13mm can switch bar hardness, pure aluminum or aluminum alloy plate should be used for low hardness Pap hardness.
