Thermoplay are introducing the new FN series nozzle family that will replace the current F series
The principal reason for this innovation is to reduce the maintenance time to replace the heater and the thermocouple, which can now be performed without having to remove the nozzle tip. The FN nozzles are available in the diameters 16, 24, 32 and 46 mm with the same standard lengths of the F- series.
Besides the versions with diameter 16, 24 and 32 mm are provided with a special bimetallic insert in titanium and tempered steel inside the tip group, thus allowing a wider area of contact with the mould. This characteristic reduces the risk of wear in the gate area and possible plastic leakage, also decreases the thermal exchange between nozzle and mould resulting in reduced power consumption.
The gate geometry of the FN series are unchanged in comparison to the F therefore can be replaced with the new nozzles without any additional machining in the mould.
