Compression and transfer moulding
WebCompression molding is a technique mainly for thermoset molding and is often used for the molding of glass fiber reinforced plastic. In the process, the molding compound is placed in the open mold cavity. The mold is closed, and heat and pressure are applied until the material is cured. High hardness steel is normally used. WebCompression molding is a manufacturing process for stock shapes, such as plates or thick sheets (Fig. 2.12). A compression molding press consists of two heated platens. The lower platen contains a recess for the plate or sheet that is charged with resin powder or granules. The platens are then pressed together and heated to consolidate the resin.
