Industrial Coil Heater Heating Elements for Injection Molding

Industrial Coil Heater Heating Elements for Injection Molding

1. 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. Structure

The main features of these heaters are 360o heated area, readily confirms to surface, fast response and quick heat transfer, helical coil design for superior performance, good resistance to corrosion and it can easily be coupled with J or K type thermocouple. The integration of temperature thermocouple for the precise temperature control. It also provides the best combination of physical strength, high emissivity and good thermal conductivity to heat hot runner bushings and nozzles.

3. Imported Raw Materials

Chinese coil heater quality has highly confirmed by the woldwide market, can compete with the top class brands, such as Hotset, GC, EURO heat etc.. The coil heater resistance is used German Nickel Chrome wire, can be coiled and straight. The insulation material magnesium oxide powder is imported from USA; which ensures the high performance, fast response time and unformity.

4. Surface Treatment

Blasting and blackening surface treatment, also can provide bright surface.

5. Coil Heates Types:

a. Cable Coil Heater

b. Mini Coil Heater:

c. Axial Clamp Coil Heater

d. Hotlock Coil Heater

e. Press in Brass Coil Heater

f. Flat Coil Heater
