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
UL temperature index
Manufacturing; Plastic injection molding
The maximum temperature below which a material maintains its electrical and mechanical integrity over a reasonable period.
Tensile strength, break
Manufacturing; Plastic injection molding
The maximum stress that a material can withstand without breaking when subjected to a stretching load.
Tensile strength, yield
Manufacturing; Plastic injection molding
The maximum stress that a material can withstand without yielding when subjected to a stretching load.
Fatigue strength
Manufacturing; Plastic injection molding
The maximum cyclic stress a material can withstand for a given number of cycles before failure occurs.
Clamping area
Manufacturing; Plastic injection molding
The largest rated moulding area an injection press can hold closed under full moulding pressure.
Recovery time
Manufacturing; Plastic injection molding
The length of time for the screw to rotate, create a shot, and return to original position.
Mould temperature
Manufacturing; Plastic injection molding
The temperature at which the mould is maintained. Often the most important benefit of raising mould temperature is that it allows a slower injection rate without the plastic getting too cold.
