Transfer & Compression Moulding

Image of Transfer & Compression Moulding

Transfer Moulding is having a "pot an plunger" to push uncured rubber into the mould cavity using hydraulic pressure which holds the mould closed while the rubber cures.  The pot and plunger are separated and the transfer mould is opened and the product can be removed.  The heat and pressures during the process form a vulcanised bond between the cable and the moulding compound.  Transfer moulding uses a closed mould, so smaller tolerances and more intricate parts can be achieved.
