Improper control of molding conditions If the injection pressure is too low, the injection and holding times are too short, the injection rate is too slow, the material and mold temperatures are too high, the part is not cooled enough, the temperature during demolding is too high, the insert temperature is too low, or there

Mold failure Since the surface of the plastic part is a reproduction of the mold cavity surface, if there are surface defects such as scars, corrosion, micropores on the surface of the mold, it will be reflected on the surface of the plastic part to cause gloss poor. If there is oily, moisture on the
