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

Available with nickel chrome steel band
Temp range for up to 400°C
Option of J type or K type thermocouple available on request
Negligible effect of material spillage
Minimum inner diameter of 25mm

Application:

Injection and blow molding
Process engineering
Extend nozzles
