 Cast-In
Heaters from Cyronix have proven to be the most effective method for
heating and cooling the barrels of extruders used in plastics processing.
Cyronix offers Cast-In-Band Heaters with liquid and/or air cooling.
Liquid cooling incorporates tubing cast in as part of the heater assembly,
allowing water or heat transfer solutions to remove the heat. Air
cooling uses fins cast to the O. D. surface for the band heater; blowers
and specially designed shrouds aid in heat removal.
Alumininum is the predominant alloy used for the Cast-In-Heaters.
Copper based alloys (Bronze and Brass) are used when the required
operating temperatures exceed the maximum for aluminum. Bronze or
brass is recommended for heated platens in molding presses as they
can withstand a greater for per square inch than aluminum. |
