polymers hot compression mould plastic products

Compression molding is usually a method of molding when the molding material, generally preheated, is first put in an open, heated form cavity. The mold is closed which has a top force or plug member, pressure is ascribed to force the material in to contact with all style areas, while heat and pressure are maintained till the molding material has cured; this process has the name compression molding method and in case of rubber it is usually known as 'Vulcanisation'. The task employs thermosetting resins from a partially cured stage, either by using granules, putty-like masses, or even preforms.

Compression molding can be a high-volume, high-pressure method worthy of molding complex, high-strength fiberglass reinforcements. Advanced composite thermoplastics can also be compression molded with unidirectional tapes, stiched fabrics, randomly oriented sheets mat or chopped strand. The power of compression molding is its ability to mold large, fairly intricate areas. Also, it is one of many lowest cost molding methods compared with other methods such while transfer molding and injection molding; moreover it waste items relatively little material, giving it an edge when working with expensive compounds.
