Product Description

Industrial Coil Heaters for Injection Molding Machine

Product Description

 

1. Coil Heater Working Principle

Flat coil heater are designed to the standard with respect to precise fit and profiling to optimize the performance of nozzles and other mating components.

They accommodate type "J" or "K" type thermocouple that could be placed internally at the tip or the middle of a heater.

They can be made as well to have profiled or distributed wattage configuration.


2 . Advantages

• Operation temperature up to 750°C (1300°F)

• 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

• Mgo insulation result in durable usage life

• High watt density
