Coil heaters

PARAMOUNT coil heaters feature continuous operating temperatures up to 1200°F (649°C). Rapid heating and cooling occur, due to the low mass construction. All heating elements are sealed from contamination and the stainless steel sheath provides maximum corrosion resistance. An optional internal thermocouple may be utilized for overtemp control.


Design Features
  • Continuous operating  temperatures to 1200°F (649°C)
  • Intermittent  operating  temperatures to 1500°F (815°C)
  • Rapid heating and cooling due to low mass construction
  • Heating elements sealed from contamination
  • Stainless steel sheath for corrosion resistance
  • Optional internal thermocouple for temperature control.

Typical Applications
  • Blow Molding
  • Custom Die Applications
  • Extrusion
  • Hot Runner Systems
  • Injection Molding
  • Thermoforming
  • Others, Consult PARAMOUNT

STANDARD NOZZLE HEATERS

The nozzle heater design was developed by PARAMOUNT Industries to provide a maximum efficiency heating device for plastic molders. Utilizing casting technology, a high performance mineral insulated heater is cast-in a bronze or aluminum alloy and machined for a precision fit onto the injection nozzle.

Design Features:

  • Precision machined ID for a precise fit
  • Stainless steel outer shell  provides for a durable protective casting
  • Optional internal thermocouple for integral temperature control
  • Copper alloy casting achieves temperatures to 1200°F ( 649°C)
  • Sealed  heater construction eliminates failures  from contamination or moisture
  • Optimum heat transfer

Typical Applications:

  • Blow Molding
  • Custom Die Applications
  • Extrusion
  • Hot Runner  Systems
  • Injection Molding
  • Thermoforming
