Service and Maintenance / Assembling the Nozzle Body and nozzle heaters
10.3.1 Assembling the Nozzle Body and nozzle heaters
1) Apply spotting ink on the nozzle body (1) bottom surface (SF1).
2) Screw in the nozzle body (1) hand-tight into the manifold thread until
seated.
3) Unscrew the nozzle body (1) from the manifold.
4) Check the matching between the manifold bottom surfaces (SF2) and
the nozzle body (1) surface (SF1).
NOTICE
The manifold must bear on all surfaces uniformly and flatly, in
particular on the nozzle head contact face.
In case of any uncertainty, clean the surfaces with a cleaning
cloth. If the next ink test is still unsatisfactory, contact
Synventive Customer Service or Technical Support.
5) With a positive ink test clean the surfaces and proceed to the next step.
6) Lubricate the thread (not the face) of the nozzle body with high-
temperature assembly paste (antiseize compound).
NOTICE
This is an important measure to prevent thread corrosion due
to aggressive gases, which could be released during plastics
processing.
