What are the reasons for the blanking hole blockage in precision stamping

When the punching material in precision stamping is soft and magnetically absorbing material, the larger the size of the blanking step hole of the punching die is, the easier it is to induce lateral frictional resistance, which eventually leads to the blockage of the blanking hole.

What is the difference between precision stamping and ordinary stamping?

The efficiency of precision stamping and general stamping are generally more than twice as fast. The main reason is that the mold structure of fine blanking is different. The development cycle is twice as long as that of single punching, and the cost is more than three times higher.

How to improve the precision of stamping parts?

1. Keep the surface of the convex and concave molds clean, and the blanks of the precision stamping parts need to be wiped clean before drawing, to avoid the unclean cleaning of the die working surface or the material surface and the inclusion of debris, which can damage the surface of the precision stamping parts and affect the quality.
