Hot Runner Spiral Coil Heater is compacted for faster and efficient heat transfer. Generally the long 20-3000mm, spring heating ring external using high quality Ni-Cr steel tube, the internal use of high purity magnesium oxide, high temperature resistance wire. With high working temperature, fast heating, uniform heating precision, long service life, can be automatically controlled area, high thermal conduction, while internal heating material damage, external can be reuses. The heaters are annealed to acquire malleability for bending into any shape. Hot runner heaters with built-in thermocouple are also available.
