Ceramic Band Heaters

MICA BAND HEATERS

Mica Band Heater

Mica Band heaters are efficient and economical solutions to the heating requirements of many applications. Mica Band heaters can attain a maximum sheath temperature of 900°F, and with various electrical termination styles, clamping mechanisms, and the ability to accommodate holes and cutouts, they are successfully used in a wide range of applications. However, they are most commonly sought after in the plastics industry.

The Mica Band Heaters manufactured by DS Heaters utilize top-grade mica types. The thickness of each mica layer is carefully selected to strike a balance between the excellent insulating properties of mica and the efficient heat transfer from the heating core to the machine barrel.

Construction

transfer from the heating core to the machine barrel. Construction The resistance wire ribbon used in the mica band heater is 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 mica band heaters are carefully rounded and formed to optimize the grip on a machine barrel. The external metallic protective sheath of Anupam’s Mica band heaters is made of a special alloy, which expands less than the barrel when heated. This difference in thermal expansion makes the heater grip the barrel firmly once it is energized. This improves heat transfer which extends the life of the mica band heater.

Mica Band Heater

  • Ensure Heater ID same as OD of cylinder/nozzle
  • Eliminate contamination of oil, plastic, dirt etc on cylinder surface to avoid carbonizing & shortening heater life
  • Secure firmly to avoid Air gap and also to compensate for normal expansion, re-tighten periodically
  • Maintain temperature controls & accessories in good working condition to avoid over heating condition
  • Protects leads from abrasion
  • Avoid process material leakage to terminal
