Metal precision stamping parts are the most commonly used parts in the field of metal processing and machinery manufacturing.Stamping parts processing is the use of mold to make the metal plate belt separation or forming processing method, the application range of the lighter windshield is very wide.

Hardware precision stamping parts of the processing process mainly includes punching, bending, drawing, forming, finishing and so on.

The processing material of metal precision stamping parts is mainly hot rolled or cold rolled metal strip material, such as alloy steel plate, galvanized plate, copper and copper alloy plate, stainless steel plate, aluminum and aluminum alloy plate.

Hardness test of hardware precision stamping parts

1. Hardness test of stamping die

Stamping die usually requires high hardness and wear resistance, heat treatment is essential.The main material of stamping die is die steel (including tool steel and high speed steel), and sometimes hard alloy.

2. Hardness test of stamping parts

Small, sophisticated metal stamping parts with complex shapes can be used to test surfaces too small to be tested on a common bench rockwell hardness tester.The PHP series portable surface rockwell durometer is ideal for testing the hardness of these precision stamping parts.The main purpose of the factory is to determine whether the annealing degree of the sheet metal purchased is suitable for the subsequent processing of the sheet metal. The processing technology of different kinds of sheet metal requires 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.
