All types of moulding employ pressure to
force material into the cavity of a mould.
The process of compression moulding,
for example, utilizes small pads of material
placed into the mould and pressure is applied
as both sides of the mould are closed. It
is therefore an ideal process for rubber materials.
Injection moulding, on the
other hand, uses material that is liquefied
from pellet form, which is then injected into
the cavity of the mould. Injection moulding
is thus perfectly suited for plastics.
Transfer moulding is similar
to compression moulding in that the material
is inserted into the mould before the pressure
is applied. However, unlike compression moulding,
it uses a closed mould, allowing for tighter
tolerances; so that more intricate parts can
be produced.
In addition to these three methods, our moulded
products can also be silk-screened
with text and graphics, autoclaved
or over-moulded.
