Micro Coil Heaters - PET

Micro Coil Heaters specially designed for smaller diameter nozzles, nozzle tips etc. These can be formed in grooves to create three dimensional heating application. Due to small diameter, these heaters are fabricated with a pressed on sheath and embedded in brass for maximum heat dissipation. 
The 1.8 mm diameter Micro Tubular Heater is formed into a coil of pre-defined specification with a unique cover (Axial Clamp) for easy fitment. The Axial Clamp enables front end loading and adaptability resulting in minimum down time caused due to heater failure in Multi Cavity Mould.

 

Features & Advantages:

  • Voltage and wattage according to application.
  • With flat and square cross-section for high efficiency due to flat surface.
  • With or without thermocouple.
  • Additional covering with clamping band or reflection tube
  • High corrosion resistance
  • Low profile construction
  • Maximum heat transfer due to more contact area.
  • Even temperature profile.
  • Precision fit on hot runner nozzles.
  • High watt density.
