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
jetting
Manufacturing; Plastic injection molding
A turbulent flow in the melt caused by an undersized gate or where a thin section rapidly becomes thicker.
toggle
Manufacturing; Plastic injection molding
A type of clamping mechanism that exerts pressure by applying force on a knee joint. A toggle is used to close and exert pressure on a mold in a press.
chopped strand
Manufacturing; Plastic injection molding
A type of fiber reinforcement consisting of strands of individual glass fibers which have been chopped into short pieces.
valve gating
Manufacturing; Plastic injection molding
A type of gate where a pin is held in the gate or channel by spring tension. As the injection stroke moves forward, this gate compresses the plastic in the runner. When this pressure build-up is ...
restricted gate
Manufacturing; Plastic injection molding
A very small orifice between runner and cavity in an injection mold. When the part is ejected, this gate readily breaks free of the runner system. Generally, the part drops through one chute and the ...
thermal conductivity
Manufacturing; Plastic injection molding
ability of a material to conduct heat.
nucleating agent
Manufacturing; Plastic injection molding
Additive used in a polymer to increase crystallization rate by providing additional sites for crystal growth (i.e. Talc). This results in faster cycle time.
