Kappa series coil heater

Kappa series coil heater

Hasteco Kappa series coil heaters is another design solution to solve the deformation of the coil heater,It and pressed in brass coil heaters are the most common method of locating heaters in a hot runner nozzle.

With this design, Coil heater is sandwiched between metal sleeves, and there are threads on one end of the outer sleeve.

  •  No tools are required for installation or removal, Kappa series coil heaters are easily replaced with a fixture pulling it out from nozzle.
  • High insulation (above 500M Ohm), high voltage resistance (above 1000V), can meet the special requirements.
