Molding compression molding (also called compression mo(u)lding), pressure plastic molding, compression molding (also known as pressing or compression molding.) is one of the main methods for thermosetting plastic processing. Sometimes used for hot plastic molding, cold plastic and rubber. The powder raw materials (such as plastic powder pressure) to the mold which is softened, and in full mold under pressure, simultaneous chemical reaction and curing, demoulding to obtain the products, usually called pressure plastic products. Especially suitable for complex shape or insert with complex products. The disadvantage is the long production cycle, low efficiency, accuracy of product size is mainly used. Manufacture of electrical parts and daily necessities such as switches, telephone parts, radio clock shell, shell, buttons and so on.
Mainly used as structural parts, connectors, guard and electrical insulation. Widely used in industry, agriculture, transportation, electrical, chemical, construction, machinery and other fields. Because of molded products, reliable quality, in weapons, aircraft, missiles, satellites have also been used.
