Metal stamping parts products forming, how to eliminate the defects scratches mould

Is the appearance of metal stamping parts have a lot of product, surface quality is very high, especially not have Nick, the pit and the bad situation, but why sometimes occurs in forming the bad situation? Reason is that when forming metal stamping parts, punch and can have friction material surface, and not the punch hard materials, so will produce scratches, how can we eliminate these scratches? First of all, we know the causes of scratches on the surface of the metal stamping, due to the relative sliding surface forming punch and materials, is bound to leave a mark on the surface, we can observe when forming product surface or internal iron filings and other foreign matter, such as burr or folding problem, these are the reasons why can cause scratches; We can also make any other changes on the mold structure, reduce friction is one way to do that, in addition, we can use the mold surface processing of titanium coating, increase smoothness, and this is a simple method, but the effect is not the best, there is also a kind of frame structure, it there is no friction, so want to completely prevent the bad situation, under the conditions allow, we could use this way to design the mould.
