Plastic compression mold

Including compression molding and injection molding two types of mold structure. They are mainly used to form thermosetting plastic mold, the corresponding equipment is a pressure molding machine. 


Compression molding method According to the characteristics of plastic, the mold is heated to the molding temperature (usually 103 ° -108 °), and then the measured pressure of plastic powder into the mold cavity and feeding room, close the mold, plastic under high heat, high pressure Was softened viscous flow, after a certain period of time curing stereotypes, become the desired product shape. 


Injection molding and compression molding is different from a separate feeding chamber, mold closed before molding, plastic in the feed chamber to complete the preheated viscous flow, under pressure to squeeze into the mold cavity, hardening molding. Compression molds are also used to shape certain special thermoplastics such as hard-to-melt thermoplastics (such as polyvinylidene fluoride) blanks (cold formed), resin lenses with high optical properties, and slightly foamed nitrocellulose steering wheels. 


Compression mold mainly by the cavity, feeding chamber, guide agencies, the introduction of components, heating systems and other components. Injection molds are widely used in the encapsulation of electrical components. Compression mold manufacturing materials and injection molds are basically the same.
