Big Diameter Press In Brass Coil Heater For Plastic Injection
Machine With Thermocouple
1. Introduction
Hot runner heater’s production length in 200-3000mm is mainly used
for hot runner mold or, as well as other precision heating system.
Spring heating ring external using high quality stainless 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, long service
life, can be automatically controlled area, high thermal
conduction, while internal heating material damage, external can
reus
Heater maximum temperature up to 650 ºC, the integration of
temperature thermocouple for the precise temperature control, can
provide K, J, E thermocouple, blasting and blackening surface
treatment, also can provide bright surface.
2. Characteristics
1) The inside insulated cover, same as the German GC.
2) Very good performance of the heating uniformity in the heating
area.
3) High insulation (more than 500M ohm) and high pressure
resistance (1000V above), can meet special requirement if customers
need.
4)The moisture-proof is IP65.
