Analysis of the nine major causes of mold burst

1. The mold material is not good, and it is easy to be broken in the subsequent processing.

2. Heat treatment: improper quenching and tempering process produces deformation.

3. The flatness of the mold grinding is not enough, resulting in flexural deformation.

4. Design process: The mold strength is not enough, the knife edge spacing is too close, the mold structure is unreasonable, the number of template blocks is not enough, there is no backing board.

5. Improper processing of thread cutting: pulling thread cutting, the gap is wrong, and the corner is not cleaned.

6. Selection of punch equipment: punch tonnage, the punching force is not enough, and the die is adjusted too deep.

7. Unsuccessful stripping: There is no demagnetization treatment before production, and there is no return pin; there are jammed materials such as broken needles and springs during production.

8. The blanking is not smooth: when assembling the mold, there is no leakage, or rolling to block the feces, and the feet block the feces.

9. Production awareness: Lamination stamping, positioning is not in place, no blow gun is used, and the template has cracks and continues to be produced.
