Hot Runner Spring Coil Heater/pipe heater 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 hot runner heaters are annealed to acquire malleability for bending into any shape. Coil tube heating elements with 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.
