Why are the stamping molds wrinkling?
The reason for the wrinkling of the stretcher is that the pressure of the elastic pressure plate is too small, or it may be too large for the extension of the groove. The solution is to increase the pressure of the elastic press and reduce the R in the concave cavity. The gap between the wrinkling and the convex and the concave is not very important.
The pressure side is small or the clearance is large, please check carefully.
The pressure side is too small, the clearance is too big, the die plane is not good. There are only a few of these
