Compression Silicone Rubber Moulding is a method of moulding in which the moulding material, generally preheated, it is first placed in an open,heated mould cavity.The mould is closed with a top force or plug member,pressure is applied to force the material into contact with all mould areas,while heat and pressure are maintained until the moulding material has cured.The process employs thermosetting resins in a partially cured stage,either in the form of granules,putty-like masses,or preforms.
