4.2x2.2mm Injection Molding Heaters Coil with Male Plug
1. Heaters Coil 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. Heaters Coil Characteristics
a. The inside insulated cover, same as the German GC.
b. High insulation (more than 500M ohm) and high pressure resistance (1000V above), can meet special
requirement if customers need.
c. Very good performance of the heating uniformity in the heating area.
d. The moisture-proof can be IP65, suitable for working in bad condition.
