reaction injection moulding requirements and definitions

Reaction injection molding (reaction injection moulding referred RIM), an industrial molding process. Forming chemical reaction in the process of an injection molding method, which is not a polymer of the raw materials used, but two or more kinds of the liquid monomer or prepolymer, a certain percentage are added separately to the mixing head, the mixing under pressure, and immediately injected into the closed mold, the polymerization and curing in the mold, shaped into a product. Because the liquid  MASTER auto moulding feedstock is used, i.e. with a small pressure to quickly fill the mold cavity, so reducing the cost of the mold clamping force and, in particular, for the production of large-area workpieces.
Reaction injection MASTER plastic injection mould  molding requires the components have been mixed, immediately rapid response, and the material can be cured to the extent of stripping. Therefore, the use of special materials and formulations, articles may need to be heat treated to improve its performance. Molding equipment is critical mixing head design, accurate measurement and delivery of components. In addition, the raw material tank and the mold temperature control is also very important.

Reaction injection moulding requires the components have been mixed, immediately rapid response, and the material can be cured to the extent of stripping. Therefore, the use of special materials and formulations, articles may need to be heat treated to improve its performance. The key reaction injection moluding equipment is mixing head design, MASTER reaction injection moulding  accurate measurement and delivery of components. The raw material tank and a mold temperature control is very important.
Reaction injection moulding is developed in the late 1970s. Using reaction injection molding method to isocyanates and polyether polyurethane made ??of semi-rigid plastic car bumpers, fenders, instrument panels. This method has the equipment investment and operating costs low, parts looks beautiful, good impact resistance, design flexibility advantages of large, 1980s developed rapidly. Reaction injection moulding can be obtained polyurethane rigid foam surface structure. MASTER injection mould design To further increase the rigidity and strength of products, the raw material is mixed with a variety of enhanced reinforcing called reaction injection molding, the product can be used for automotive exterior body panels, hood. Newly developed cultivars with an epoxy resin, dicyclopentadiene polymer, silicone resin, and an interpenetrating polymer network.
