Home    Mica Band Heater

Mica insulated band heaters are installed on cylinder forms such as barrels, pipes and nozzles of injection molding or extrusion machines.


Mica insulated band heaters can be constructed in a variety of dimensions, voltage and wattages with different options such as holes, cut-outs and notches. A number of terminals, wire lead options and terminal boxes offer great flexibility for field wiring. With sheath temperature capabilities of up to 800°F, these heaters are ideal for plastic processing applications.


BRIGHT HEATER adopts a stringent internal quality control system. Every heater is tested for resistance and dielectric.
