Coil heater description:
Coil heater's production length in 200-3000mm is mainly used for hot runner mold or, as well as other precision heating . Spring heating ring external using Ni-Cr steel tube, the internal use of high purity magnesium oxide , high temperature resistance wire, and first-class manufacturing technology . The wire is after the annealed, with flexibility can be bent into an arc or circle heating. Its high working temperature, fast heating, uniform heating precision, long service life, can be automatically area, high thermal conduction, while internal heating material damage, external can reuse.
