Industrial hot runner nozzles coil injection molding heater in
brass
Description:
1) GME 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
Ni-Cr 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
reuse.
2) GME manufactures high quality minitubular heaters that assure
the best with respect to safety and performance. Minitubular heater
owes it importance to his great versatility; the possibility to
reach high working temperatures in small spaces allows to support
the most difficulit needs. GME's minitubular heater can be
manufactured with differents lengths, powers and sections, and are
avaliable from stock also with thermocouple built-in (type J).

Application:
1) Hot runner Injection moulds.
2) Hot Runner Nozzles & Bushings
3) Medical, analytical equipments
4) Packaging machineries
5) Other precision heating systems
Features:
1) A very wide contact surface results in exceptionally high levels
of thermal conductivity towards the body that needs to be heated.
2) Optimal insulation results in very long life duration.
3) Heavy-duty construction results in very high resistance to
mechanical shocks.
4) Operation temperature up to 700°C (1300°F).
5) Optional built-in thermocouple for high-resolution temperature
measuring (J-type standard; K-type on request)
6) Unlimited range of possible shapes obtained from the straight
heater.
Heaters can be incorporated into brass or aluminium castings.
