  • Cartridge Heaters

    Magnum™ cartridge heaters are swaged designs, made for use in applications where high watt density, high temperatures and long service life are critical to minimize mold service downtime and expensive press open time. The swaged construction produces a highly compacted unit that resists shock and vibration, while providing for maximum element life through efficient transfer heating. They last up to 20 times longer than uncompacted cartridge heaters. UL/CUL Component Recognition Available. Durex will also custom manufacture to your specifications.

    • Cartridge Heaters, Duraslik Non-Stick
      Cartridge Heaters, Duraslik Non-Stick
      The Duraslik non-stick coating eliminates the need for additional release agents to be applied to the heater prior to the insertion. The non-stick coating acts as a corrosion inhibitor and a solid lubricant on the inner diameter of the drilled hole when the heater is energized, allowing for reduced downtime…
