What is plastic compression moulding mould?
Compressed-plastic mould is mainly used to form a kind of mould for thermosetting plastic, and its corresponding equipment is pressure forming machine.
Compression molding method is based on the characteristics of plastic mold is heated to molding temperature (generally in 103 ~ 180 ℃), and then measuring good molding powder into the mold cavity and loading chamber, the closed mold, plastic under heat and pressure are softening sticky flow, after a certain period of time the curing finalize the design, become the shape of the required products.Injection molding and compression molding different room is equipped with a separate charging, forming mold before closing, plastic sticky flow in interior finish feeding preheating, the pressure under the action of high speed extrusion mold cavity, hardening of the shape.Compression mold is used for molding some special thermoplastic plastics such as difficult to molten thermoplastic (ptfe) blank (cold pressing molding) and high optical performance of the resin lenses, mild foaming cellulose nitrate car steering wheel, etc.The die - casting mould is mainly composed of cavity, feeding chamber, guide mechanism, ejection part and heating system.Injection moulds are widely used to encapsulate electrical components.The material used in the manufacture of the die is basically the same as the injection mould.
