The molding process uses the characteristics of each stage of the resin curing reaction to achieve product molding, that is, the molding material is plasticized, flowing and filled with the mold cavity, and the resin is cured. In the flow process of the molded material filled with the mold cavity, not only the resin flows, but also the reinforcement material flows, so the molding pressure of the molding process is higher than that of other process methods, which belongs to high pressure molding. Therefore, it requires both a hydraulic press that can control the pressure and a metal mold with high strength, precision and high temperature resistance
