Plastic injection molding technology
The cause and solution to burrs at the beginning stage of plastic injection machine work and plastic shortage after work for some time
At the beginning stage of plastic injection machine work, due to the long heating of melting plastic material inside the feed pipe of machine, the viscosity of metling plasitc material is low with good flowability, the molded plastic part are easy to have burrs (flashs) on them. After the machine works for some time, the melting plastic material continuously bring the heat away from the feed pipe, there is not enough melting plastic material supply, the viscosity degree increase, the flowability is not good, plastic shortage is common scene.
Solution: Increase the feed pipe temperature gradually after the plastic injection machine work for some time.
