Custom plastic mold

Custom plastic mold Is mainly used for forming a class of thermosetting plastic mold, its corresponding device is a pressure molding machine. The plastic properties of compression molding method, the mold is heated to a molding temperature (typically 103 ° -108 °), then good measure pressure plastic powder into the mold cavity and feeding room, closed mold, high fever, high pressure in the plastic It was softening viscous flow, after a certain time curing stereotypes, into a desired shape of the article. Pressure china plastic injection molding and compression molding except that no separate feeding room, before forming the first closed mold, plastic interior completion in the feed preheat was viscous flow state, under pressure to adjust to squeeze into the mold cavity, hardening molding.
