Metal Stamping processing is a sophisticated technology that involves many details. In this process, we should pay attention to the following points:

1. Process review of metal stamping parts. After the preliminary determination of the hardware drawings, the punching process calculation should be carried out according to the specified die of the selected punching equipment, and whether it can ensure the quality and dimensional accuracy requirements of the parts should be checked.

2. Pay attention to the difficulties in deep drawing during the metal stamping process. Due to the significant influence of the relative thickness of the material on the degree of deep drawing deformation and ultimate deformation, a smaller die fillet radius should be used as much as possible during deep drawing.

3. Prevent the occurrence of waste products in metal stamping processing. During the stretching process, it is necessary to regularly check whether there are obvious burrs on the stamped parts.

4. Attention should be paid to preventing tearing and deformation during metal stamping processing. When bending, correction bending and center bending should be used as much as possible.

5. Prevent scratches during metal stamping processing. To avoid this defect, scratches should be added to the corresponding mold or the working surface of the mold should be repaired.
