A rubber compression moulding machine uses a combination of pressure and heat to form rubber into a desired shape. A heated moulding tool and a press's gripping force are used to mold the rubber. Vulcanization is the process through which the rubber undergoes chemical changes before cooling and the extraction of the finished component. Large items requiring a substantial amount of material to make are best suited for this type of molding. You can see different components, such as pins, plates, etc., on a rubber compression moulding machine that are all necessary for the proper molding of a rubber product.
