smc high precision houseroof compression mould

Compression molding is often a method of molding in which the molding material, generally preheated, is first put into an open, heated mould cavity. The mold is closed with a top force or outlet member, pressure is ascribed to force the material towards contact with all pattern areas, while heat as well as pressure are maintained till the molding material has cured; this process is called compression molding method and if of rubber it's also known as 'Vulcanisation'. Doing this employs thermosetting resins in a very partially cured stage, either in the form of granules, putty-like masses, and also preforms.

Compression molding is often a high-volume, high-pressure method suitable for molding complex, high-strength fiberglass reinforcements. Advanced composite thermoplastics is usually compression molded with unidirectional tapes, woven fabrics, randomly oriented sheets mat or chopped strand. The power of compression molding is its ability to pattern large, fairly intricate pieces. Also, it is on the list of lowest cost molding methods balanced with other methods such since transfer molding and injection molding; moreover it squanders relatively little material, giving it an edge when working with high-priced compounds.
