Cartridge Heaters

Superior Heat Transfer Insertion Heaters for Platens and Molds

  Our high temperature swaged units are manufactured with magnesium oxide insulation. Every cartridge heater uses a premium quality Incoloy® sheath which offers a higher temperature rating and higher resistance to chemical corrosion.  Welded end disc made from the same material as the sheath provides a positive seal against moisture and other contaminants.   

  High-grade Nickel-Chrome resistance wire precisely wound on a high purity magnesium oxide core places the resistance wire as close to the inside of the sheath as possible.

  A high purity Magnesium Oxide powder is used to fill all remaining space inside the sheath. The heater is then swaged, which compacts the magnesium oxide grains into a solid mass.
