Mini-Coil Band Heaters

Tempco's replacement round cable mini-coil heaters for OEM Hot Runner Systems are designed and manufactured under tight tolerances and specifications.

±2% Resistance Tolerance
5" and 7" Staggered Cold Lead Length
72" Insulated Lead Wire Length White/Black for 250W and White/Red for 125W

Mini-Coil Band Heaters have two types of clamping: Screw operated clamping (shown in first image to the right) for the traditional style and Cam Operated Clamping (shown in second image to the right).
Cam Operated Axial Clamping allows tool room personnel to replace the heating element or the thermocouple of the gate bushing without having to remove the bushing from the mold. This can even be done in emergencies while the mold is still in the press, saving hours of downtime. The hex head cam is accessed from the front, parallel to the bushing’s shaft.
