Coil Heaters

 Coil heaters are used in hot runner moulds, sprue bush and on nozzles.

 

They provide a wide contact area which helps in achieving high levels of heat transfer and thermal conductivity.

 

Working temperature of 700 deg C is attainable and the optimal insulation helps in achieving long life.

 

These can be offered with an inbuilt J-type or K-type thermocouple. Also, these can be incorporated into Brass or Aluminium castings for increased mechanical strength.

 

The cross sections offered by us are 3mm x 3.3mm and 2.2mm x 4mm. These are available in staright lengths and are coiled as per the customer's requirement.
