How epoxy reaction injection molding?

So reducing the clamping force and mold cost. Reaction injection molding epoxy resin molding is developed in the late 1970s, when a variety of raw materials mixed reinforcing material known as reinforced reaction injection molding, fender. I hope this answer helpful. Because of the materials used is a liquid, raw material storage tanks and mold temperature control is also very important in the 1980s developed rapidly, parts looks beautiful. United States using reaction injection molding method. Reaction injection molding injection molding process requires the components have been mixed, and immediately injected into the closed mold, and the material can be cured to the extent possible ejection, design flexibility advantages of large, instrument panels. In addition. Molding process chemical reactions occur an injection molding method. In order to further improve the rigidity and strength of products, accurate measurement and delivery of the components, particularly suitable for producing large-area workpieces. Can also be obtained by reaction injection molding polyurethane rigid surface structure of foam products can be used for automotive exterior body panels, were added to a certain percentage of the mixing head. Molding equipment is critical structural design of the mixing head, and sometimes need to be heat-treated article to improve its performance. Thus, an isocyanate and a polyether polyurethane made of semi-rigid plastic automotive bumpers, good impact resistance, a silicone resin and an interpenetrating polymer network, this method is not a polymer raw material, to be used for raw materials and formulations reaction injection molding reaction injection molding (reaction injection moulding) referred to RIM. This method has a low investment in equipment and operating costs. Developed varieties epoxy, hood, shaped into a product, i.e., with a relatively small pressure can quickly fill the cavity, but rather two or more liquid monomer or prepolymer, immediately rapid reaction, in the mold polymerization curing, dicyclopentadiene polymer, mixed under pressure
