1. precision metal mold material is not easy to fracture during subsequent processing

2. heat treatment: quenching and; tempering process of improper deformation

3. precision metal mold grinding; plane is not enough produce deflection

4. design process: precision metal; mold manufacturing, mold strength is not enough, the blade spacing is too close, the mold structure is not reasonable, not without template number

5. line cutting processing plate stepping; improper: pull wire cutting, no gap, stamping die design, did not make clear angle selection of equipment:

6. punch; press tonnage, blanking force is not enough die too deep

7. stripping bad: no demagnetization; before production, no materia L return shoots; broken needle broken spring card material production;

8. male Michael: no leakage of feces assembled mold, or roll plugging plugging shit shit, stepping;

9. production consciousness: lamination stamping, positioning not in place, no use well * * *, the template has the crack still continue to produce;
