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 ...

Injection mold construction is the process of creating molds that are used to perform injection molding operations using an injection molding machine. These are generally used to produce plastic parts using a core and a cavity. Molds are designed as two-plate or three-plate molds, depending on the type of component to be manufactured.
ASA can be made by either a reaction process of all three monomers (styrene, acrylonitrile, acrylic ester) or a graft process, although the graft process is the typical method. A grafted acrylic ester elastomer is introduced during the copolymerization of styrene and acrylonitrile. The elastomer is introduced as a powder. [11]
