Hot Runner Coil Heaters With Integratged Thermocouple And SS
Braided Protection Sleeve
1. Coil Heater Brief Introduction
Coil heaters are made of nickel chrome resistance wire placed
inside chrome nickel steel tube filled with MgO powder and
compacted for faster and efficient heat transfer. 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.
