Hot runner brass pipe heater nozzle heater pressed with coil heater for plastic injection molds
Description:
1) Hot runner heater are made of nickel chrome resistance wire placed inside chrome nickel steel tube filled with MgO power and compacted for faster and efficient heat transfer. The heaters are anneale to acquire malleability for bending into any shape. Hot runner heaters with built in thermocouple are also avaiable. Hot runner bushes are produced with hot runner heaters of different cross section with inner brass and outer stainless steel cover
2) Length of Hot runner heater within 20-3000mm 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 .
3)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 controlled area, high thermal conduction, while internal heating material damage, external can be reuses.
