Description
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.
