Injection Molding

Injection molded parts (3) used w/investment castings and stampings in a completed assembly

Injection molding is a manufacturing process for producing parts from both thermoplastic and thermosetting plastic materials. 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 the part cools and solidifies, the mold is opened, and the part is ejected. No chemical reaction occurs during this molding process.

The characteristics of this process include utilizing a ram or screw type plunger to force molten plastic into a mold cavity. It produces a solid or open-ended shape that conforms to the contour of the mold. After a product is designed, usually by an industrial designer or an engineer, molds are produced from metal, usually either steel or aluminum, and precision machined to form the features of the desired part. Injection molding is widely used in a wide variety of industries: automotive, appliance, computer, communication and industrial equipment.
