Molded
Rubber Parts Processes include compression molding, transfer molding, and
rubber injection molding.
Compression Molding
l It is best used for low to medium production volumes for larger
parts where tightest tolerances
and flawless finishes are not required.
l Compression 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
be removed
Transfer molding
l It 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
low
l Transfer 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
of
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
removed.
Rubber Injection Molding
l Rubber injection molding is most effective
for a high-volume manufacture of small parts that
require high tolerances and
little or no finishing after production
l Injection 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
Extruding Capabilities:
Offers extrusions capabilities for Rubber extrusion,
thermoplastic extrusion, and silicone extrusion.
