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
Mineral reinforcements
Manufacturing; Plastic injection molding
Inorganic substances used as filler for plastics. Some common examples are: clay, mica, talc.
Tool
Manufacturing; Plastic injection molding
In injection molding, the term sometimes used to describe the mold.
Closed-loop control
Manufacturing; Plastic injection molding

Manufacturing; Plastic injection molding
Term used to describe the maximum unit stress a material will withstand when subjected to an applied load in a compression, tension, flexural, or shear test.
Pellets
Manufacturing; Plastic injection molding
Tablets or granules of uniform size, consisting of resins or mixtures of resins with compounding additives which have been prepared for moulding operations by extrusion and chopping into short ...
Izod impact test
Manufacturing; Plastic injection molding
Test to determine impact strength of a sample by holding a sample bar at one end and broken by striking. Sample specimen can be either notched or unnotched.
Plasticity
Manufacturing; Plastic injection molding
The ability of a material to withstand continuous and permanent deformation by stresses exceeding the yield value of the material without rupture.
