- Resin transmission molding is a process method of infiltrating the resin into the closed mold and solidifying the material and solidifying. This technology can effectively reduce equipment costs and molding costs without pre -immersion and hot pressure tanks. In recent years, this technology has developed rapidly. It has been widely used in the fields of aircraft industry, automobile industry, and ship industry. It has studied the development of various branches such as RFI, VARTM, SCRIMP, and Sprint to meet the application needs of different fields.
- The squeezing is to press the blanking material placed in the concave mold with the punch or convex mold to cause a plastic flow, so as to obtain a pressure processing method of the molded pore or bump shape of the mold. During squeezing, the gray material produces three -way compression stress, and even a low -plastic gray can be squeezed and shaped.
- Thermal formation is a special plastic processing method that processs thermoplastic plastic sheet into various products. Processing thermoplastic plastic sheet into a special plastic processing method of various products. The sheet is heated on the frame to softened. Under the action of external forces, it is close to the mold of the mold to obtain the shape of the same surface. After cooling, it will become a product after repair.
- Hand paste is also known as hand -mounted and forming and forming. It refers to hand -made operations on the mold that is applied to the mold. CICF and release of this process of plastic products.
