摘要：

In injection molding, the ejection forces decrease when the surface roughness of mold decreases. However, the election forces increase contrary in the area of surface roughness is less than 0.2 mu mRa. Several kinds of PVD films are coated on the mold cores to prevent the increasing of ejection farces. Some of these PVD films showed effective prevention of increasing of ejection forces.
