Often seen as the most basic method of rubber moulding, compression mould tooling is generally lower in cost than injection mould tooling. Therefore, it is common for customers with lower quantity requirements to use this option for low volume products.
Rubber compression moulding requires a carefully measured amount of uncured rubber to be loaded into the bottom section of the preheated moulding tool. The two halves of the tool are brought together, forcing the rubber material to conform to the shape of the tool cavity. The material is compressed and heated over a pre-determined time, during which the material cures (or vulcanises) and solidifies into the desired shape. The two halves of the tool are then opened and the newly created rubber part is removed.
