Coil Heaters

Coil heaters are designed to deliver high watt densities in a concentrated area. Typical electric coil heater applications include plastics injection molding nozzle heaters, small heat transfer pipe heating, hot knife heaters, and concentrated chamber heating.

Coil heaters are also referred to as cable heaters. These electric heating coils are used in blow molding, plastics extrusion, injection molding, thermoforming, hot runner systems, and custom die applications. A coil heater can provide rapid heating and cooling due to its low mass construction, and coil heating elements are sealed from contamination. The sheath of a coil heater can be made to be corrosion-resistant in very harsh environments.
