Compression Transfer Molding
A modified form of compression molding, Compression
Transfer Molding incorporates certain benefits of both the
compression molding and injection molding worlds.
The difference between compression and compression
transfer is that in compression molding the material is pre-measured
and hand-loaded into the actual mold cavity before closing the press
where as with compression transfer the mold is closed and the
material is loaded into a central pot on the back side of the mold
that connects to a runner system which feeds the mold cavity or
The benefits are that the material does not need to
be measured as accurately, more cavities can be molded at a time and
the "flash" or overflow of excess material is reduced. These factors
directly translate into saving the customer money.
Most of our compression molding machines are
capable of both compression and compression transfer molding and
have been since 1943.
