Plunger Process Control PPC


Full Plunger Motion Monitor

The Plunger Process Control System (PPC) monitors individual full plunger motions during the parison forming process. The system uses full stroke sensors and a unique method to eliminate cabling in the plunger mechanism.

As well as measuring plunger stroke for the NNPB and PB processes, gob weight is automatically controlled with closed loop technology to adjust tube height and individual plunger needles in the feeder.

The display shows by cavity the full plunger stroke profile allowing optimization of the press time and plunger up profile. All profiles are stored electronically and all data is easily displayed.

Most recent developments included plunger position profiles for BB process, allowing a visualization of the plunger operation for the first time. All the features enable the production specialists to optimize the forming process, reduce variability and improve quality.
