Ceramic Band Heater Manufacturing
Performance, Temperature & Applications
Caldor Heat Engineering designs and manufactures ceramic band heaters with precision engineering and rigorous quality control to support demanding industrial heating applications. These heaters feature a ceramic insulated core and rugged metal cladding, producing superior thermal transfer and longevity under continuous use.
Our ceramic band heaters are specifically engineered to deliver uniform heat distribution and rapid thermal response — qualities essential for processes requiring consistent and stable temperature control. Thanks to the ceramic insulation, these elements can withstand elevated operating temperatures typically up to 450°C in standard configurations, with custom options available to meet higher thermal requirements.
Ideal applications include cylindrical components such as barrels, pipes, and nozzles, where targeted heating is crucial for efficiency and product quality. Ceramic band heaters are widely used in industries such as plastics processing, packaging, and other high-heat industrial environments.

A ceramic band heater is an industrial heating device specifically designed to heat cylindrical components such as pipes, barrels, extruder cylinders, and nozzles. It is constructed around a flexible ceramic insulation core, which is enclosed within a robust metal sheath, typically manufactured from steel or stainless steel. Heat is generated by passing an electric current through the heating element, causing the ceramic insulation to heat up and efficiently transfer thermal energy to the surface of the component being heated.
Ceramic band heaters are widely used across a broad range of industrial processes, including plastic injection molding, extrusion, packaging machinery, and food processing equipment. They are valued for their high thermal efficiency, excellent heat transfer characteristics, and ability to maintain stable, uniform temperatures over extended operating periods. Their design allows them to withstand high operating temperatures and perform reliably in harsh industrial environments, while remaining relatively easy to install and service.
One of the key advantages of ceramic band heaters is their low thermal mass, which enables rapid heat-up times and quick response to temperature adjustments. This results in improved process control and reduced energy consumption. In addition, ceramic band heaters are highly versatile and customizable, allowing them to be manufactured to fit standard or irregular shapes and specific application requirements. With a long service life and minimal maintenance needs, they represent a dependable and cost-effective heating solution for demanding industrial applications.
