Sealed Nozzle Band Heater

Sunil Heaters And Controls offers Sealed Nozzle Band Heater. Sunil Heat has designed sealed mica nozzle band heater to prevent the failure of nozzle heaters against the leakage & contamination of plastic material at nozzle position. These heaters meet the required temperature prior to molding at nozzle position. These heaters are hermetically sealed during the manufacturing process. The connection between the heating element & the leads is protected by a special terminal cap made of brass 1mm thick. The terminal cap is brazed which allows a high mechanical strength in the most delicate area of the heater i.e. the termination. The heating of nozzle in injection machines is still a big problem owing to subsequent stops of the production process and cost incident. They have seen a large series of cases causing an early failure most of them are due to plastic leakage impregnating the heater and causing heater failure. These problems are solved by using our sealed mica nozzle band heaters. There can be custom built entry points for termination considering customers requirement, alternative tubular nozzle heaters are available.
