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.

Add a new termContributors in Plastic injection molding
Plastic injection molding
ultimate strength
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.
spiral flow
Manufacturing; Plastic injection molding
Test performed by injection molding a sample into a spiral mold and used to compare the processability of different resins.
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.
elasticity
Manufacturing; Plastic injection molding
The ability of a material to quickly recover its original dimensions after removal of a load that has caused deformation.
compressive strength
Manufacturing; Plastic injection molding
The ability of a material to sustain a force in a direction opposite of tension.
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.
abrasion resistance
Manufacturing; Plastic injection molding
The ability of a material to withstand mechanical actions such as rubbing, scraping, or erosion, that tend progressively to remove material from its surface.
