Adjust the equipment: adjust the pressure, speed and other parameters of the equipment to ensure that the contact between the stamping part and the die is uniform.

Change the mold structure: optimize the structure of the mold, reduce the sharpness of the corners and corners, and relieve the pressure.

Adjust the process parameters: by adjusting the process parameters properly, reduce the operator error and reduce the possibility of stamping parts indentation.

Optimize the material: the material used is optimized accordingly and the material with better performance is selected, which can effectively improve the wear resistance and compression resistance of the stamping parts and reduce the appearance of indentation.

Correct maintenance of equipment: regularly overhaul and maintain the equipment, and timely clean up the internal residue of the equipment to ensure the normal operation of the equipment.

These measures can help effectively reduce the problem of stamping parts, but the specific improvement methods need to be determined according to the specific situation.
