Q: Why does molded piece appear the bad appearance of flaking of the surface layer?

Answer: Injection molded parts appear on the surface of the poor appearance, the reason is that the plastic formula of the injection molded parts after forming the incomplete fusion, or the plastic formula (including additives) after forming the repulsive splitting appearance. Check or change the plastic additive mixture first. Check and optimize screw rotation speed to reduce injection speed. Popcocon’ plastic production of plastic pumping granules in strict accordance with the mature formula production, so the plastic pumping granules are to ensure the material of high purity, no impurities.Put an end to the bad phenomenon of surface layer.
