draft Design of SMC Mold Release
1. The draft design of SMC products when demoulding
Since the SMC product shrinks after cooling, the product tightly encloses the SMC mold core and the raised portion of the cavity. In order to facilitate the smooth removal of the product and to prevent it from hitting or scratching the product during demoulding, when designing the SMC product, both the inner and outer surfaces should have sufficient draft angles along the stripping direction.
2, in the design, should pay attention to the following two aspects:
1 When molding larger SMC products, it is required that the internal surface demoulding slope is greater than the external surface demolding slope;
2 commonly used draft stripping value of 1.1 to 1.5 degrees, can also be as small as 0.5 degrees.
