Industrial Electric Coil Heaters

Electric Coil heaters are also referred to as spiral heaters, cable heaters, hot runner nozzle heaters, spring heaters, hot sprue heaters, which are made of nickel chrome resistance wire, MgO insulation and thin metal shell (usually made of stainless steel, later annealed). Though often found in a spiraling or winding shape, a hot runner coil heater is named refers to the resistance wire inside the heater that has a small winding pattern throughout the length of the heater. 

The electric coil heaters are mainly used to heat injection molding, rods, molds and nozzles for fast and efficient heat transfer. Generally, they are produced in straight bar and tightened in production with different diameter and pitch according to customer needs. They can be made of square, rectangular or round sections. The electric coil heaters with thermocouple are available.
