Product Specification
Mica Band Heater

Features
  • Excel's Mica Band Heaters are widely used to heat the molds, dies, nozzles and especially to heat the cylinders (barrels) on all types of plastic(s) processing machinery
  • The mica heater is most economic
  • It provides excellent dielectric strength
  • It provides excellent thermal conductivity as heat transfer is by "conduction".
  • Due to its best heat transfer capability, faster heating up and cooling down is possible
  • Maximum sheath temperature up to 480oC (900oF).
  • Maximum watt density = 25 watts / square inches
  • Note: In case where high watt densities are required, it is important that. All heaters should be used with appropriate, approved and precise temperature control/sensor device(s)
  • The built in insulation is specially fomulatled for the excellent heat reflection and performance capabilities
  • The low mass heaters give the best controllability. The lower the thermal mass, lesser time required to deliver the heat to the object to the heated. Due to low mass and high conductivity the "Polymer Melt" is heated quickly. Resulting auto tune function on a control works best.
  • Flexible one o two - piece design makes installation faster and easier. It flexible construction also allows the heater to be opened to the full diameter of the cylinder
  • The most common square, rectangular and hex shaped mica heaters can be manufactured as per your specifications in one or two piece units. Available with leads or terminals.
  • Excel's exclusive method of designing, maximizes the element wire coverage of the heated area. This results in uniform heat distribution and longer heater life.
  • The heater meets progressive requirements of the plastic processors.
