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
Continuous service temperature
Manufacturing; Plastic injection molding
The highest temperature at which a material can perform reliably in long term application - as defined by the manufacturer.
Cross-linking
Manufacturing; Plastic injection molding
The formation of chemical links between the molecular chains in polymers. This process can be achieved by chemical reaction, vulcanization, and electron bombardment.
Stationary platen
Manufacturing; Plastic injection molding
The large front plate of an injection moulding press to which the front plate of the mould is secured. This platen does not move during normal operation.
Proportional limit
Manufacturing; Plastic injection molding
The greatest stress which a material is capable of sustaining without deviation from proportionality of stress and strain. (Hooke's Law).
Linear thermal expansion
Manufacturing; Plastic injection molding
The fractional change in length of a material for a unit change in temperature.
Ram
Manufacturing; Plastic injection molding
The forward motion of the screw in the plasticator barrel that forces the melt into the mould cavity.
Shear stress
Manufacturing; Plastic injection molding
The shearing force divided by the area. It is always a maximum at the outside of the flow channel. As it is force-related, it depends on the viscosity of the material, which in turn depends on the ...
