74 Gate-Mate Hot Sprue Bushings
Medium Gate-Mate ®

The Medium Gate-Mate Bushing is designed for direct part gating in single cavity molds,
eliminating the conventional cold sprue. The unique design of the bushing provides
minimal gate vestige, without the objectionable witness lines so commonly found
on direct gated parts.

The bushing transfers molten plastics from the machine nozzle to the mold cavity
via a direct channel in the body. The bushing, in conjunction with the recommended
tip and gate configuration, controls gate vestige height.

The Medium Gate-Mate Bushing utilizes an advanced design square coil heater and
an independent thermocouple, strategically located for precise temperature control.
