Cast-In Band Heaters
As a standard, Cast-In Band Heaters are manufactured in aluminum alloys because this material provides very good thermal conductive properties. For applications requiring higher operating temperatures and/or higher watt densities, bronze or brass alloys can be used.
Cast-In Band heaters can be made with one of two cooling methods: Liquid-cooled or Air-cooled. Used heavily in plastics extrusion processes, the cooling function within our cast-in band heaters is important for maintaining the proper temperature of the barrel.
Precision machining of the band heater's inside diameter yields superior heat transfer between the heater and machine barrel and is finished to customer specifications.
