Hot Runner Electric Coil Heater with K Type Thermocouple

1. Coil Heater Brief Introduction

Wuhan Global Metal Hot Runner Electric Coil Heater with K Type Thermocouple use Germany heater wire,

United States high purity magnesium oxide material, and strict process technology. There are various cross

section and size for choice, such as square, round and flat, provide high performance electric heater for

heating hot runner mold and other fields.

Heater maximum temperature up to 650 ºC, the integration of temperature thermocouple for the precise

temperature control, can provide K, J, E thermocouple, blasting and blackening surface treatment, also can

provide bright surface.

2. Coil Heater Application

This electric coil Heater is widely applied for hot runner system, plastic industry, packaging machinery, medical

equipment, casting process,other electric heating industry, etc..

3. Coil Heater Characteristics

a. The inside insulated cover, same as the German GC.

b. Very good performance of the heating uniformity in the heating area.

c. High insulation (more than 500M ohm) and high pressure resistance (1000V above), can meet special

requirement if customers need.

d. The moisture-proof can be IP65, suitable for working in bad condition.
