The application scope of metal stamping parts:

Special stamping enterprises. For example, stamping of aviation parts belongs to this kind of enterprise, but these craft factories also belong to some large factories.

Stamping of spare parts in automobile and other industries. It is mainly formed by punching and shearing. Many enterprises in this sector belong to scale parts factories, and some independent stamping factories. At present, there are many such small factories near some automobile factories or tractor factories.

Stamping plant for daily necessities. Do some crafts, tableware, etc. These factories have also made great progress in recent years.

Stamping in automobile industry. Deep drawing is the main method. In our country, this part mainly concentrates in automobile factory, tractor factory, aircraft manufacturer and other large factories. Independent large-scale stamping and drawing plants are rare.

Electrical parts stamping plant. This kind of factory is a new industry, which develops with the development of electrical appliances. This factory mainly concentrates in the south.

Stamping Plant for Home Appliance Parts. These factories are in our country after the development of household appliances, most of them are distributed in household appliances enterprises.

Detection of metal stamping parts:

Rockwell hardness tester is used for hardness testing of metal stamping parts. Small stamping parts with complex shapes can be used to test the plane is very small and can not be tested on ordinary desktop Rockwell hardness tester. Stamping process includes blanking, bending, drawing, forming, finishing and other processes. Stamping materials are mainly hot-rolled or cold-rolled (mainly cold-rolled) metal 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.

PHP series portable surface Rockwell hardness tester is very suitable for testing the hardness of these stamping parts. Alloy stamping parts are commonly used parts in the field of metal processing and mechanical manufacturing. Stamping parts processing is a method of separating or forming metal strips by means of dies. Its application range is very wide.

The main purpose of hardness testing of automotive stamping materials is to determine whether the annealing degree of the purchased metal sheet is suitable for the subsequent stamping process. Different kinds of stamping process require different hardness levels of sheet metal. Aluminum alloy sheet used for stamping can be tested by Wechsler hardness tester. When the thickness of material is more than 13mm, it can be changed to Barkhault hardness tester. Pure aluminium or low hardness aluminium alloy sheet should be used by Barkhault hardness tester.

In the stamping industry, stamping is sometimes called sheet metal forming, but it is slightly different. The so-called sheet metal forming refers to the use of sheet metal, thin-walled tubes, thin profiles and other raw materials. The forming method of plastic processing is generally called sheet metal forming. At this time, the deformation in the direction of thick plate is generally not taken into account.
