Service and Maintenance / Assembling the Nozzle Tip on the Nozzle
10.3.3 Assembling the Nozzle Tip on the Nozzle
10.3.3.1 Assembly of the common Nozzle Tip
1) Apply spotting ink on the nozzle tip (8) bottom surface (SF1).
2) Screw in the nozzle tip (8) hand-tight into the nozzle body (1) until
seated.
3) Unscrew the nozzle tip (8) from the nozzle body (1).
4) Check the matching between the nozzle body surface (SF2) and the
nozzle tip surface (SF1).
NOTICE
All contact surfaces (SF2 and SF1) of the nozzle must be
clearly visible on the outer edge, especially on the contact
surface of the nozzle tip (SF1).
NOTICE
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 tip body with high-
temperature assembly paste (anti-seize compound).
NOTICE
This is an important measure to prevent thread corrosion
due to aggressive gases, which could be released during
plastics processing.
