Plastic compression molds

Plastic compression molds Including compression molding and injection molding press two structures mold type. They are mainly used for forming a class of thermosetting plastic mold, its corresponding device is a pressure molding machine. Compression molding method according to the plastic properties, the mold is heated to a forming temperature (typically 103 ° -108 °), and then a good measure pressure plastic powder into the mold cavity and the loading chamber, closed mold, high fever, high pressure in the plastic viscous flow was softening, after a certain time curing stereotypes, MASTER wheel covers molding shape into a desired product. Pressure injection molding and compression molding is different from a separate feed chamber to the mold is closed before plastic injection mold makers molding, the plastic in the feed was preheated Interior Finish viscous flow state, extruded under pressure to adjust the mold cavity and hardening the molding. Compression molding of thermoplastic mold also used some special molten thermoplastic such as the difficulty (such as poly vinyl fluoride) blank (cold forming), high optical performance resin lenses, slight foaming nitrocellulose car steering wheel, etc. . MASTER plastic rattan garden furniture mold   Compression molds mainly by the cavity, chamber, guide mechanism, introduced parts, heating systems and other components. Pressure injection molds are widely used for packaging of electrical components on. Pressure plastic mold manufacturing and injection molds used basically the same material.
