20mm barrel spring type brass coil heater heating element for mould
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 sent 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,while internal heating material damage,external can be reuses.
Specification:
1.simple structure
2.long-time usage
3.high efficient heater exchange
4.it could easy to bent into many kinds of shape
5.good insulation could withstand high voltage
