2.2x4.2mm nozzle spiral coil heater for hot runner systerm with metal mesh lead wire
Description:
1) Length of coil heater within 20-3000mm is mainly used for hot runner mold,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 flxibility can 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 careuses.
