Electric Hot Runner Brass Heater For Injection Mold

Hot Runner Coil Heater is mainly used for hot runner mold or, as well as other precision heating system. Spring heating ring external using high quality 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, Iong-term service life, can be automatically controlled area, high thermal conduction, while internal heating material damage, external can be reuses.
