Factors Influencing The Hardening Speed Of Injection Molding
May 18, 2017

The hardening speed of injection molding parts and the varieties of the molding materials, the shape of plastic parts, wall thickness, molding temperature and whether preheating and pre pressure are closely related, such as the use of pressure ingot, preheating, improve molding temperature and increasing pressure time, can significantly accelerate the hardening speed. In addition, the hardening speed of the injection molding process should also be suitable for the molding method. For example, when injecting or injection molding, it should be required in plasticizing, filling when chemical reactions slow, hardening slow, has maintained a long time flowing state. In addition, when the cavity is filled with the high temperature and high pressure, it should be hardened rapidly. Plastic Injection molding process hardening slow molding cycle will make longer, lower production rate, hardening faster plastic, can not be formed into complex injection molding parts. Therefore, the hardening speed of injection molding parts must be strictly controlled during processing.
