Injection Mould Brass Tube Electric Heaters for Hot Runner System
1. Electric Heaters 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.
