smc high precision electricity box compression mould

Compression molding is really a method of molding in which the molding material, generally preheated, is first slipped into an open, heated form cavity. The mold is closed using a top force or plug member, pressure is utilized by force the material straight into contact with all mold areas, while heat plus pressure are maintained until the molding material possesses cured; this process is recognized as compression molding method and should of rubber it is usually known as 'Vulcanisation'. The process employs thermosetting resins within a partially cured stage, either by using granules, putty-like masses, or perhaps preforms.

Compression molding is usually a high-volume, high-pressure method worthy of molding complex, high-strength fiberglass reinforcements. Advanced composite thermoplastics may also be compression molded with unidirectional tapes, woven fabrics, randomly oriented sheets mat or chopped strand. The bonus of compression molding is usually its ability to form large, fairly intricate areas. Also, it is on the list of lowest cost molding methods offer other methods such when transfer molding and injection molding; moreover it waste items relatively little material, giving it an edge when working with overpriced compounds.
