silicone rubber high precision bumper compression mould

Compression molding is usually a method of molding when the molding material, generally preheated, is first placed in an open, heated mould cavity. The mold is closed which has a top force or connect member, pressure is applied to force the material in contact with all mould areas, while heat along with pressure are maintained until finally the molding material possesses cured; this process is named a compression molding method and should of rubber it is also known as 'Vulcanisation'. The method employs thermosetting resins in the partially cured stage, either comprising granules, putty-like masses, as well as preforms.

Compression molding may be a high-volume, high-pressure method ideal 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 benefit of compression molding will be its ability to pattern large, fairly intricate parts. Also, it is one of the lowest cost molding methods offer other methods such seeing that transfer molding and shot molding; moreover it squanders relatively little material, giving it an edge when working with overpriced compounds.
