Compression Moulding process

Compression moulding is a manufacturing process in which a pre-determined amount of moulding materials are pre-heated and compressed into the desired form using two heated mould cavities. It is a high-volume, high-pressure moulding technique for complicated, high-strength fibreglass reinforcements. Thermoset composites are the most common type of material used in compression moulding & SMC is a thermoset material. It has the advantage of being able to mould large, fairly complex parts. Furthermore, when compared to other moulding methods such as transfer moulding and injection moulding, it is one of the least expensive; additionally, it wastes relatively less material, giving it an advantage when working with expensive compounds. Manufacturers who are used to working with metal parts will find it very simple to convert a metal object into a compression moulding part.
