Ceramic knuckle band heaters.

Excellent dielectric strength at high temperatures with high voltages. To order or enquire. Knuckle band heaters the knuckle band a segmented ceramic band heater was designed by fast heat to provide evenly distributed heat on extrusion and injection moulding barrels. Typical lead time for ceramic knuckle heaters is 3 5 days for small items 7 10 days for more complex units.

We confirm manufacturing lead times at the time of quotation. Ceramic knuckle heater delivery time. Consequently the width of a ceramic band heater ban falls within a certain incremental range. Unlike all other types of band heaters the knuckle ceramic metal heater heats by radiation.

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. Ceramic fiber insulation and a stainless steel jacket or shroud cover this assembly. A helically wound resistance coil made from nickel chrome wire is precisely strung through specially designed ceramic insulating bricks forming a flexible heating mat. Home products ceramic band heaters configurations.

Ceramic band heaters by thermal corporation provide long life and use less wattage because of insulation in plastics extrusion and injection molding applications. 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 insulated knuckle band heaters with ceramic band clamps conserve energy by using a 1 4 thick ceramic fiber insulating blanket reducing power consumption by 25 to 30 percent. Best suited for low to moderate temperatures the knuckle band is constructed of precision made segmented ceramics in order to add flexibility and allow for easy installation.

Ceramic band heaters knuckle band heaters description in a ceramic band heater nickel chrome wire is embedded in a flexible outer wall made of special interlocking ceramic tiles which are assembled like a brick wall. Ceramic band heaters are made by using different combinations of ceramic tiles which are available only in specific lengths. Because of the low thermal conductivity of the ceramic fiber insulation the external surface temperature of the ceramic band clamps and heater is approximately 400ºf while running the inside surface. When used on injection moulding machine barrels it can be provided with a metal insulation jacket with 12 5mm ceramic fibre insulation for energy savings of up to 25 resulting in reduced power consumption and cooler working conditions.
