Compression Moulding

Compression moulding as a method of moulding in which the moulding material, generally preheated, 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 cooled. The advantage of compression moulding is its ability to mould large, fairly intricate parts. Also, it is one of the lowest cost moulding methods.
