In the automobile industry, the body, chassis, fuel tank, radiator film, boiler drum, container shell, motor, electrical iron core silicon steel sheet are stamping processing. Instrumentation, household appliances, bicycles, office machinery, life utensils and other products, there are a large number of stamping parts.

Precision stamping parts and castings, compared to a thin, uniform, light, strong Stamping can be made by other methods difficult to manufacture with stiffeners, ribs, undulating or flanging of the workpiece to improve its rigidity. As a result of precision molds, the workpiece accuracy of up to micron, and repeat high precision, consistent specifications, you can punch out the hole nest, bumps and so on. Stamping sheet surface and the inherent performance of the quality of finished stamping a great impact on metal stamping processing of stamping materials have the following requirements:

Stamping sheet surface and the inherent performance of the quality of finished stamping a great impact on metal stamping processing of stamping materials have the following requirements:

1.stamping material thickness accurate, uniform;

2.the surface smooth, no spots, no scars, no scratches, no surface cracks;

3.yield strength uniform, no obvious direction;

4.the average elongation is high;

5.Processing hardening.

Stamping processing is an efficient production method, the use of composite mold, especially the multi-station progressive die, can be completed in a press punching process, to achieve by the material open-book, leveling, punching to the forming, finishing Fully automated production. High production efficiency, good working conditions, low costs, the general production capacity is hundreds of pieces per minute.
