Injection compression molding is a high-grade form of conventional injection molding. It can increase the ratio of the length of the flow stream/the wall thickness of the injection molding part; smaller clamping force and injection pressure are adopted; the internal stress of the material is reduced; and to improve the process productivity. The injection compression molding is suitable for various products made of thermoplastic engineering plastics, such as large-size curved parts, thin-wall and miniaturized parts, optical lenses and parts with good anti-attack characteristic requirements. Injection compression molding generally involves injecting a molten polymer into a mold cavity, so that the polymer in the mold cavity is always kept under a certain pressure, and when the polymer is close to a full mold cavity, the mold cavity is further compressed so that the molten polymer is further compressed and reaches the required finished thickness of the part.
