Plastic injection molding
Plastic injection molding is the primary process for manufacturing plastic parts used in consumer goods such as computer keyboards, monitors, bottle caps, cups and solid plastic articles. Plastic is known to be a very versatile and economical material that is used in many applications. Injection molding involves taking plastic in the form of pellets or granules and heating this material until a melt is obtained. Then the melt is forced into a split-die chamber/mold where it is allowed to "cool" into the desired shape. The mold is then opened and the part is ejected, at which time the cycle is repeated.
