76 Gate-Mate Hot Sprue Bushings

Jumbo Gate-Mate ®

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