Heating Coil

INTRODCTION

Hot runner heater are made of nickel chrome resistance wire placed inside chrome nickel steel tube filled with MgO power and compacted for faster and efficient heat transfer. The heaters are anneale to acquire malleability for bending into any shape. Hot runner heaters with built in thermocouple are also avaiable. Hot runner bushes are produced with hot runner heaters of different cross section with inner brass and outer stainless steel cover.
Avaliable in following cross section
3.0*3.0, 3.3*3.3, 3.5*3.5, 4*4 etc
4.2*2.2, 4.2*2.5
