Industrial Spring Stainless Steel Heating Coil Electric Hot Runner
Heater
Description:
1) 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 .
2) 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.
