Micro Coil Heater for Injection Mold Hot Runner System
1. Micro Coil Heater Brief Introduction
Wuhan Global Metal hot runner coil heater 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. Micro Coil Heater Characteristics
a. Very good performance of the heating uniformity in the heating
area.
b. The inside insulated cover, same as the German GC.
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.
