Micro Coil Heater

Micro Coil Heater

DHE offers the highest quality hot runner coil heaters that are made from nickel chrome resistance wire that is inserted into chrome nickel steel tube full of MGO powder and compressed for faster and more effective heat transfer. Our Micro coil heater is annealed so that it becomes malleable and can be bent into any shape. We produce hot runner bushes with different cross section hot runner heaters with inner brass covering and outer stainless steel covering. The Micro Coil Heater is an efficient heater designed for use with smaller diameter nozzles and nozzle tips.
