Axial Clamp Coil Heaters 3 / 4 Inch Inner Diameter For Hot Runner Nozzle

3/4“ inner diameter Axial Clamp Coil Heaters For Hot Runner Nozzle with thermocouple

Description

Coil and cable heaters are made by placing a pair of tiny coils or two lines of straight resistance wire inside a very dense MgO medium. This core is then inserted into a stainless steel shell. These high-performance heating cells can acquire temperatures of up to 1500° F.

The heaters are annealed to acquire malleability for bending into any shape. Hot runner heaters with built in thermocouple are also available. Hot runner bushes are produced with hot runner heaters of different cross section with inner brass and outer stainless steel cover.It's 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 be reuses.
