Ceramic Band Heaters

American Process Heat's Ceramic bands are manufactured here in the USA.  Our ceramic bands are custom manufactured to match the OEM specs and quality.  American Process Heat Ceramic bands are rated to 1200° F.  They are used on Injection Molding Machine Barrels as well as on Extrusion lines. 

Ceramic Band Heater with Terminal Box

Ceramic Band Heaters by American Process Heat provide long life and use less wattage (because of insulation) in plastics extrusion and injection molding applications. These band heaters are constructed with a stainless steel shroud enclosing high quality ceramic knuckles through which run coiled high temperature nickel-chromium element wire. Configuration choices allow selection of one or two piece heaters, type of closure, and type of leads/post terminals. Diameters of 2-1/4″ or greater and widths of 1″ to 15″ are available. Leads normally exit 180° from gap. Lead length tolerances are as follows: ± 1″ (up to 72″) and ± 2% (over 72″). Options include terminal boxes, holes, Heat Saver (extra) insulation, 3-phase power, dual voltages, partial coverages, European connectors, perforated sheaths without insulation for air cooled applications, and others (see list below). To order, specify quantity, configuration, inside diameter, width (increments of 1/2″), wattage, voltage, lead length if applicable and any options.  Have Questions?

Advantages of Ceramic Band Heaters

  • Lower Operating Cost – Because of superior insulation, less heat escapes to the air and less wattage is required to maintain barrel temperature. Also the heater is safer because the external surface is much cooler.

  • Operator Comfort – With the majority of the heat going directly to your process, the ceramic knuckle band heater gives off significantly less heat to ambient air than a mica band heater.

  • Longer Heater Life – because all materials used are rated to operate at very high temperatures.

  • Higher Operating Temperatures

  • Flexible – easy to install and remove

  • Dual Heat Transfer – Heat is transferred through both radiation and conduction so a near perfect fit is not required as with other heaters, such as mica heaters.
