HOT RUNNER MICRO COIL HEATERS
Elmec hot runner micro 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 micro-coil 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 the different cross-section with inner brass and an outer stainless steel cover.
