 Injection
molding is a manufacturing technique for
making parts from both thermoplastic and
thermosetting plastic materials in
production.
Molten plastic is injected at high pressure
into a mold, which is the inverse of the
product's shape.
After a product is designed by an Industrial
Designer or an Engineer, molds are made by a
mold maker (or toolmaker) from metal,
usually either steel or aluminum, and
precision-machined to form the features of
the desired part.
Injection molding is widely used for
manufacturing a variety of parts, from the
smallest component to entire body panels of
cars. Injection molding is the most common
method of production, with some commonly
made items including bottle caps and outdoor
furniture.
Materials
The most commonly used thermoplastic
materials are polystyrene (low cost, lacking
the strength and longevity of other
materials), ABS or acrylonitrile butadiene
styrene (a co-polymer or mixture of
compounds used for everything from Lego
parts to electronics housings), nylon
(chemically resistant, heat resistant, tough
and flexible - used for combs),
polypropylene (tough and flexible - used for
containers), polyethylene, and polyvinyl
chloride or PVC (more common in extrusions
as used for pipes, window frames, or as the
insulation on wiring where it is rendered
flexible by the inclusion of a high
proportion of plasticiser).
Injection molding can also be used to
manufacture parts from aluminum or brass.
The melting points of these metals are much
higher than those of plastics; this makes
for substantially shorter mold lifetimes
despite the use of specialized steels.
Nonetheless, the costs compare quite
favorably to sand casting, particularly for
smaller parts.
