Elmecspeciality Micro Coil Heaters are similar to the coil heaters but with a similar cross section and clamping band over the heater to ensure the perfect snug fit .which results in efficient heat transformation. The problem of material spillage results in frequent failure of mica nozzle heaters, whereas these heaters are robust in such conditions.
