Mold is becoming increasingly popular in production with high volumes. It is sure that there are various methods in the coursework of the molding process, such as the transfer molding and injection molding. The compression molding is a specific way as well. It is a forming process, in which a plastic material is placed directly in to a heated metal mold, then is softened by the heat, and forced to conform to the shape of the mold as the mold closes.

Its process starts with a fixed amount of plastic or gelatin inserted in to a heated mold. Then a top force is necessary to close the mold. Afterwards, pressure and heat are applied in to forcing the inner materials in to contact with all mold areas and ought to be maintained in the work of the whole process until the molding material has cured. Then, it is time to wait till the objects being cooled. The ideal shape for the product has done indeed. It is to have seen that the process is a high-volume, high-pressure process suitable for molding complex, high-strength fiberglass reinforcements.

Apart from these, there's other points it needs to be improved. The poor product consistency and difficulty in controlling broken and being not suitable for some types of parts are some of them. In order to make full use of the compression molding, there's six points that the engineer or the designer ought to keep in mind. They are to choose the proper amount of material, the maximum amount of energy necessary to heat the material, and the appropriate heating technique ought to, to foretell the necessary force to be definite that shot attains the proper shape, to design the mold for fast cooling after the material has been compressed in to the mold.
