Ceramic Insulated Band Heaters, Custom Knuckle Band Heaters
Ceramic band heaters and custom ceramic insulated band heaters or otherwise known as knuckle band heaters are suitable for plastics injection molding, extrusion, blow molding and blown film equipment as well as for other commercial and industrial applications including heating of pipes, cylinders and tanks. Ceramic knuckle band heaters offer lower operating cost - because of superior insulation, less heat escapes to the air and less wattage is required to maintain barrel temperature. Ceramic fiber insulation reduces power consumption by 20% to 30%. Ceramic heater bands offer higher operating temperatures and longer heater life, because all materials used are rated to operate at very high temperatures. In addition, knuckle heaters offer 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. Due to the fact that the majority of the heat is going directly to your process, the ceramic band heater gives off significantly less heat to ambient air than a mica band heater.
National Plastic Heater provides ceramic band or knuckle insulated heaters with standard and heavy duty insulation options. We also can customize knuckle band heaters with holes, cut-outs and partial coverage options as well as various clamping and termination styles.
Successfully positioned in domestic trade, National Plastic Heater is also engaged in the business of exporting industrial process electric heaters, temperature sensors (thermocouples and rtd's), temperature control panels and solid state relays (SSR's) to OEM's, R & D Specifiers, Plastics and Rubber Industries, Machine Fabricators, Universities and End Users.
NPH ceramic insulated band heaters are a critical component for major manufactures operating in industries such as plastics, rubber, packaging, foodservice and a variety of other commercial and industrial applications.
