The Cause Of Errors Or Permanent Failures Will Occur In Advance

- Jun 11, 2018-

1) the material problem of the main working parts of the mould and improper selection. The material has bad performance and no wear resistance; the die steel has not been refined, and has a large number of smelting defects; the convex and concave die, the forging process of the forging blank is not perfect, and the remains have the hidden trouble of heat treatment.

2) the problem of die structure design, and the structure of stamping die is unreasonable. The slender punch has no design reinforcement device, the discharge port is not smooth, there is a pile up, the unloading force is over, the ambassador mold is subjected to alternating load increasing and so on.
