MASTER custom injection moulding Reaction injection molding

MASTER custom injection moulding  Reaction injection molding (reaction injection moulding referred RIM), MASTER plastic injection toy mould  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, MASTER crate mold  and immediately injected into the closed mold, the polymerization and curing in the mold, shaped into a product. Because the liquid 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.
