Application of Rubber Injection Molding Press in Vulcanization of EPDM

Abstract: The application of two different types of rubber injection molding press (A-type and B-type) in the vulcanization of ethylene propylene diene monomer (EPDM)was compared. A-type injection molding press was suitable for pure rubber products, while B-type injection molding press was suitable for rubber products with complex structures and metal inserts. During production, the problems such as difficulties in feeding, leakage of the rubber material, mold sticking and concave shrinkage holes at the injection port of the finished product, could be solved by improving the feeding port,changing injection parameters,cleaning the mold, and applying Teflon.
