Matrusree designs & manufactures variety of Band Heaters, That are most commonly used in the plastic injection molding and extrusion processes machines. Use as low a watt density rating as your application permits. A close match of the heat supplied to the actual requirements will reduce temperature overshoot, reduce cycling and increase the life of any band heater you use.
Four basic Band Heater constructions are illustrated here:
- Mica Band & Nozzle Heaters
- Ceramic Band Heaters
- “Insulation Tech” Power Saving Heater
- Air-Cooled Ceramic Band with blower Jacket
Mica Band & Nozzle Heaters:
Matrusree’s mica band is a proven heater design for good life efficiency and dependability. It assures maintaining the lowest winding temperatures possible, keeping a low-mass heating element assembly for fast heat-up and quick response to controls.
A specific, nichrome or kanthal ribbon wire is wound on specially selected mica grade providing even heat distribution for maximum heater life. Mica of proper thickness is then used to insulate the windings that provide excellent thermal conductivity and dielectric strength .The element pad is now enclosed in a specially treated rust-resistant steel sheath casing that provides the best combination of physical strength, high emissivity and good thermal conductivity to heated cylindrical parts.
