Injection molding is a process of injecting plastic materials into the mold to create a part. Injection molding can also be used in metals, glass and elastomers. The desired materials are fed into a hopper then into the barrel, where it is mixed and forced into a mold cavity. After it cools and hardens, the material is now formed into the configuration of the mold.
