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

Spiral flow

Manufacturing; Plastic injection molding

Test performed by injection moulding a sample into a spiral mould and used to compare the processability of different resins.

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.

Conditioning

Manufacturing; Plastic injection molding

Subjecting a material to standard environmental and/or a non-standard stress state prior to testing or use.

Compressive strength

Manufacturing; Plastic injection molding

The ability of a material to sustain a force in a direction opposite of tension.

Shear strength

Manufacturing; Plastic injection molding

The maximum load required to shear the specimen in such a manner that the moving portion has completely cleared the stationary portion. Sheet Sheets are distinguished from films in the plastics ...

Fabricating

Manufacturing; Plastic injection molding

The manufacture of plastic products by appropriate operations. This includes plastics formed into moulded parts, rods, tubes, sheeting, extrusion and other forms by methods including punching, ...

Flexural strength

Manufacturing; Plastic injection molding

The maximum stress in the outer fibre at the moment of crack or break. In the case of plastics, this value is usually higher than the tensile strength.
