Low & Medium Watt Density Cartridge Heaters

  • The heater design consists of helically wound resistance coil made from nickel-chrome wire, evenly stretched and strung through holes in a round ceramic insulator. The element assembly is inserted into a Chrome Nickel Steel/Brass sheath. This alloy provides the best combination of physical strength and resistance to heat oxidation .
  • Specially selected grain size and high purity magnesium oxide is used to fill all remaining space inside the ceramic insulator to increase thermal conductivity, dielectric strength, and provide longer operating heater life.
  • Cartridge heaters are used for heating metal parts and can also be fitted with threaded bushings for liquid heating for certain applications.

High Watt Density Cartridge Heaters

Cartridge heaters can be considered "component heaters" that are used to heat up many different applications. Primarily used in mould, these heaters fit snug inside a cavity and helps heat solids by reaching high temperatures. Cartridge heaters have the versatility of being able to carry thermocouple inside to help control temperatures of the heater more accurately. Various diameters allow for it to be used in any cavity and can be custom designed with any cold section. Lead wires extend from the end to your controls.
The construction of high temperature cartridge heaters positions a nickle-chrome resistance wire precision wound around a magnesium oxide core. It is a inserted into a stainless or Incoloy tube locating the resistance wire close to the sheath. The core is centrally positioned within the tube and filled with magnesium oxide powder. Nickle pins pass through the centre of the core making contact with the resistance wire at bath ends. The whole is assembly is highly compacted by a swaging operation and thus ensuring excellent heat transfer to the external sheath. One end of the heater is closed with a welded metal end-disc and wire leads exit at the opposite end which is typically closed with a lava seal. A variety of wire leads and lead protection options are available. Heaters can be supplied with internal thermocouples, mounting fittings and many other options.
