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).
