What are metal stamping parts?

The hardness test of metal stamping parts adoptsĀ  hardness tester. Small, complex-shaped stampings can be used to test small planes that cannot be tested on ordinary benchtop hardness testers. The PHP series of portable surface Rockwell hardness testers are ideal for testing the hardness of these stampings. Alloy stamping parts are the most commonly used parts in the fields of metal processing and machinery manufacturing. Stamping processing is a processing method that uses a mold to separate or form a metal sheet. Its application range is very broad.

The processing of stamping parts includes blanking, bending, deep drawing, forming, finishing and other processes. The materials for stamping parts are mainly hot-rolled or cold-rolled metal sheet and strip materials, such as carbon steel sheets, alloy steel sheets, spring steel sheets, stainless steel sheets, copper and copper alloys Plate, aluminum and aluminum alloy plate, etc.

1. Hardness testing of stamping materials

The main purpose of the hardness testing of stamping materials is to determine whether the annealing degree of the purchased metal sheet is suitable for the subsequent stamping processing. Different types of stamping processing techniques require sheets of different hardness levels. The aluminum alloy plate used for stamping parts can be tested with a Webster hardness tester. When the material thickness is greater than 13mm, a Barcol hardness tester can be used instead, and a barcol hardness tester should be used for pure aluminum plates or low-hardness aluminum alloy plates.

2. Hardness testing of stamping die

The main material of stamping die is die steel , and sometimes cemented carbide is used.

Usually, the three most important steps in a stamping factory are shearing, punching/cutting, and folding.
