including processes for a wide range of elastomeric materials: EPDM rubber,
nitrile rubber, neoprene rubber,
silicone rubber and thermoplastic vulcanization.
Rubber Parts Processes include compression molding, transfer molding, and
rubber injection molding.
lIt is best used for low to medium production volumes for larger
parts where tightest tolerances
and flawless finishes are not required.
lCompression molding is defined by taking a pre-measured amount of
raw rubber material that is placed
into a heated open lower mold cavity. The
top cavity is then forced closed, causing the raw material to
flow through the
shape of the mold. After curing, the mold cavity is opened
and the shapes can
lIt is used for products that require a good
surface finish and tight dimensional & mechanical stability.
And allows for
flexible design and rapid manufacturing of parts while keeping production costs
lTransfer molding is a form of rubber
production in which the raw material is measured, heated
and then forced into
chamber. A plunger is used to force the material into the mold using a system
runners and channels to thoroughly fill the closed mold. The mold is heated
to cure the raw material.
The mold is then opened and the molded parts can be
Rubber Injection Molding
lRubber injection molding is most effective
for a high-volume manufacture of small parts that
require high tolerances and
little or no finishing after production
lInjection molding is a manufacturing
process accomplished by taking raw, uncured rubber
and forcing it into a heated
mold using a reciprocating screw.
The material is formed and cured under heat
and pressure, then removed to cool as a custom shape
Offers extrusions capabilities for Rubber extrusion,
thermoplastic extrusion, and silicone extrusion.
