Product Description

 Hot runner Press In Brass Nozzle Heaters

Product Description

 

1. Coil Heater Working Principle
Electric Coil heater, also known as cable heater, convert electricity into heat through the process of Joule heating. Electrical current running through the element encounters resistance, resulting in heating of the element.

2. Coil Heater Structure
Press in brass coil heater, the coil heater is designed to beset in the brass sheating, can eliminate known problems associated with the casting process.

The machined path in the brass for the heater enables exact repeatability of heat profile. By never exposing the coil heater to molten brass there are no risks of shifted heater coils, or destruction of the thermocouple junction.

Flexible design options include internal, external "wound in" or external slotted type J or type K thermocouples.

For OEM application, HT-Elite can customize the brass sheathing upon request.
