Product Description

Electric Heater Coil for Injection Mold Hot Runner

 

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

1. Flexible cold section
2. Higher watt density than a cable heater
3. Sealed transition head for moisture resistant applications available
4. Resistance wire centered for more repeatable heat profile
5. Outside sheath to improve heating efficiency
6. Temperatures up to 1800°F (982°C)
7. Precise temperature control
8. Built-in type J or K Thermocouple
9. Rugged, durable construction
10. Unheated straight section
11. Choice of lead protection
12. Made to customer specifications

4. Coil Heater Imported Raw Materials

a. The coil heater resistance is used German Nickel Chrome wire, can be coiled and straight.

b. The insulation material magnesium oxide powder is imported from USA; which ensures the high performance, fast response time and good unformity.

5. Coiling Option:

   Cylindrical                                       Flat Coiling                    Conical coiling

 


Exit Options:
Tangential                   Axial                 Radial



6. Termination:

Plain leads with high temperature sleeve


High temperature lead wire with a fiberglass jacket exiting from a transition bracket, which sealed with high temperature cement.

Stainless steel braided


The stainless steel braid, provides abrasion resistance and maintains high flexibility.
