Many engaged in stamping parts custom of people have encountered in the production of mold plate cracking problems, general situation was jumping off a small gap, or crack, serious when mould plate cracking, directly from stamping custom to stamping into finished products and the relevant;
The custom mould pressing crack and what problems are concerned, we know the: stamping custom die blanking is not well when usually die work in the assembly is no leakage of material, block wall material, the most vulnerable to this problem;
Stamping custom design process is not accurate, die strength is not enough, die blade too close, unreasonable structure, will result in the crack of the mould;
Stamping custom die blank plate during heat treatment process is undeserved, billet deformation, or die oxidation during quenching heat treatment on skin and decarburization, can also lead to bad mold plate cracking, etc. , we can use the vacuum quenching to deal with.
Stamping custom mould billet surface without sand, surface roughness, usability and accuracy of mould;
Improper wire-cutting technology, gap no processing accuracy, no do clear Angle, which reduces the surface hardness, a microcrack, may also affect the mould durability in addition to these, of course, when we mold custom easy problems, we will also because of some mistakes when we produce influence mold damage, cause not durable, next time we can continue to discuss the
