PLASTIC INJECTION MOLDING

Injection Molding Process

Injection molding is the most commonly used manufacturing process for the fabrication of plastic parts from both thermoplastic and thermosetting materials. The material is fed into a heated barrel, mixed, and forced into a mold cavity where it cools and hardens to the configuration of the cavity. After a product is designed, usually by an industrial designer or an engineer, molds are made by a mold maker (or toolmaker) from metal, usually either steel or aluminum, and precision machined to form the features of the desired part. Injection molding is widely used for manufacturing a variety of parts, from the smallest component to entire body panels of cars.
