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.

Plastic injection molding
bulk density
Manufacturing; Plastic injection molding
A measurement of mass per unit volume of materials (such as powders) that describes the effects of the particle packing density.
compression molding
Manufacturing; Plastic injection molding
A method of molding in which the molding material, generally preheated, is placed in an open heated mold cavity, the mold is closed with a top force, pressure is applied to force the material into ...
compound
Manufacturing; Plastic injection molding
A mixture of resin(s) and additives usually formed in a separate machine downstream forn the primary reactor.
multi-cavity mold
Manufacturing; Plastic injection molding
A mold having two or more impressions for forming finished items in one machine cycle.
split-ring mold
Manufacturing; Plastic injection molding
A mold in which a split cavity block is assembled in a channel to permit the forming of undercuts in a molded piece. These parts are ejected from the mold and then separated from the piece.
hot-runner mold
Manufacturing; Plastic injection molding
A mold in which the runners are insulated from the chilled cavities and are kept hot. Hot-runner molds make parts that have no scrap.
family mold
Manufacturing; Plastic injection molding
A mold that produces non-identical parts simultaneously from multiple cavities.
