Tempco is widely recognized as the industry leader in manufacturing Cast-In heater/coolers for the plastics industry. Our capabilities and the application possibilities for utilizing Cast-In Heater Technology extend far beyond the scope of plastics machinery.
Tempco has set industry standards by creating custom designed Cast-In Heaters of every imaginable size, shape and electrical rating that can safely and practically address the diversified requirements of industrial and commercial markets.
Cast-In Ring Heaters are frequently used in Blown Film Die, Extrusions Die, Screen Changer and Extruder Barrel Adapter applications where long life and minimal maintenance concerns are prevalent.
The design scope of this product line makes it possible to cast large or small diameter disc shaped rings with nominal thicknesses of 3/4" to 1". These units are an excellent choice for heating the top or bottom of a cylindrical die.
As a standard, Cast-In Ring Heaters are generally manufactured in aluminum because of its superior thermal conductivity. For higher temperature or high watt density requirements, bronze or brass alloys can be used.
