Reaction injection molding (RIM) is similar to injection molding except thermosetting polymers are used, which requires a curing reaction to occur within the mold. Common items made via RIM include automotive bumpers , air spoilers , and fenders .
Impinging mixers combine and disperse resins within each other, and are often used in reaction injection molding (RIM). Mixing occurs as two high velocity streams collide in a mixing chamber. High velocity results in a turbulent rather than a laminar flow. Impingement mixing is most effective when it occurs at the center of the mixing chamber.
Injection moulding (U.S. spelling: injection molding) is a manufacturing process for producing parts by injecting molten material into a mould, or mold. Injection moulding can be performed with a host of materials mainly including metals (for which the process is called die-casting ), glasses , elastomers , confections , and most commonly ...

This is an important difference from other reaction injection molding (RIM) systems, such as polyurethane, since the reaction is not stoichiometric. The 1:1 volume ratio for DCPD molding is not critical since this is not a combination of two different chemical elements to form a specific matrix. However, significant changes in ratio will slow ...
