  • Main reasons for rebound of waste

1. The sharpness of the cutting edge. The larger the fillet of the cutting edge, the easier it is to cause the scrap to rebound.

2. The insertion modulus of the mold. When stamping dies at each station, the requirements for the input modulus are certain. The input modulus is small, which is easy to cause rebound of waste materials.

3. Whether the die clearance is reasonable. Unreasonable die clearance is easy to cause scrap rebound.

4. Whether there is oil stain on the surface of the plate to be processed.
