Plunger Up Control

FlexIS Plunger Up Control adjusts the Plunger Up motion in Press & Blow productions. The system takes care for having the cavity filled entirely with glass at the desired time.


The result of this continuous adjustment is a well maintained full contact time throughout the production run and across all cavities of the machine (see picture above – situation before and after switching on). Customers report that also the start up after a job change is greatly supported by the system – Plunger up adjustment is automatically done within a few cycles.
