Band Heaters are efficient and economical solutions to the heating requirements of many applications. They can attain a maximum sheath temperature up to 1000°F, but with different electrical termination styles, clamping mechanisms, and ability to accommodate holes and cutouts, mica band heaters are successfully used in many applications, but are mostly sought for in the plastics industry.
Band Heaters utilize different types of top grade mica. The thickness of each mica layer is carefully selected in order to balance between the insulating characteristics of mica and the ease of heat transfer from the heating core to the machine barrel.
The resistance wire ribbon used in band heaters are not restricted to the capabilities of nichrome wire. Different alloys are considered for different applications. The internal winding is carefully designed to ensure uniform heat distribution throughout the band heater. To maximize the surface to surface contact, our band heaters are carefully rounded and formed to optimize their grip. The external metallic protective sheath of our band heaters are made of a special alloy, which expands less than the barrel when heated. This difference in thermal expansion makes the heater grip firmly once it is energized. This improves heat transfer which extends the life of the heater.
Band Heater Applications:
- Barrels of plastic injection molding and extrusion machines
- Maintain or add additional heat to cylindrical pipes, dies or molds
- Packaging machinery
- Chemical or food processing
