Hot Runner Coil Heater Electric Heating Element Industrial Heaters
Product Description
1.Nozzle Heater Working Principle
4.2x2.2mm Spring Hot Runner Nozzle Heater, also known as cable heater, coil heaters, 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.Nozzle Heater Structure
The main features of Nozzle 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.Nozzle Heater Imported Raw Materials
Chinese coil heater quality has highly confirmed by the worldwide 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 uniformity.
4.Nozzle Heater Surface Treatment
Blasting and blackening surface treatment, also can provide bright surface.
5.Nozzle Heater Cross Section
Based on specific requirements and applications, coil heaters are manufactured in different cross sections. Each one is having its own advantages and disadvantages. Basically there are three types of coil heaters.They are
| Coil Heater Cross Section |
| Round Coil Heater Diamater |
Diameter 3.0, 4.0,5.0 |
| Square Coil Heater Diamater |
3.0x3.0, 3.3x3.3, 3.5x3.5, 4.0x4.0, 5.0x5.0 |
| Rectangular Coil Heater Diamater |
4.0x2.0, 4.2x2.2, 4.5x2.7 |
