Reaction injection molding (RIM) is similar to injection molding except thermosetting polymers are used, which requires a curing reaction to occur within the mold. Since the raw material is liquid, so it is quick to fill the mold with small pressure. It can reduce the cost of mold, particularly suitable for large production of parts.

In early times, reaction injection molding is used for polyurethane material. With the development of technology, reaction injection molding can also be applied to a variety of materials such as epoxy, nylon, polyurea, and poly cyclopentadiene. This method make low equipment investment and low operating costs. The parts manufactured have beautiful loook, good impact resistance, and flexibile design. To get further rigidity and strength of the product, a variety of raw materials are mixed to reinforce reaction injection molding. Sometimes, these products may need to be heat treated to improve its performance.
