Plunger Process Control - PPC

in Hot End » Process Products
  • PPC provides a complete visualization of the parison forming for Narrow Neck Press and Blow as well as Wide Mouth Press and Blow
  • The system records continuously the entire plunger stroke on all cavities across the machine
  • PPC also provides a precise gob weight control through automatic feeder tube height adjustment and optional needle height adjustment
  • The wireless connection from base plate adapter to plunger mechanism with full stroke sensor eliminates the risk of cable damages

 

Gob weight control

The PPC gob weight control algorithm provides close loop gob weight control adjusting the feeder tube height and as an option the feeder plunger needle height. This provides stable gob weight which is a requirement for good NNPB and PB production.

Wireless Connection

The wireless connection between the plunger sensors and the adapter plate is avoiding damage or destruction of cables during cylinder exchanges. The cables don’t need to be unplugged for the mechanism change.

Quick conversion 4 ¼ TG - 6 ¼ DG

The AIS provides the capability to convert the machine within less than six hours from 4 ¼ TG to 6 ¼ DG, which can be maintained with PPC. During the conversion no base plate, no PPC adapter plate and not even a cable must be changed. This is possible due to the unique wireless signal transmission.

Software supported process analysis

PPC comes with very powerful diagnostic software and a user friendly interface allowing analyses of a single cavity profile up to literally hundreds of detailed profiles. The system analyses all press curves and visualizes the result color coded for a good understanding of the process. Loading and Press End position are also constantly tracked and recorded.

PPC with Automatic HEWR

Continuously increasing demands from fillers can be met with the PPC. Analyzing parameters such as plunger end position, press duration and variations of the plunger position, provide a tool to reject defects already at the hot end.

Process data collection and Connection with Plant Information System

The software also allows all monitored data to be collected and stored easily and quickly recalled and displayed with user defined acceptable ware thresholds.

The Plunger Process control can be connected with Plant Information System existing plant information systems, closing the loop to a plant wide quality control

Equipment Tester

The PPC Equipment Tester supports the plant repair, maintenance and production. It provides trouble shooting possibilities which allows the production staff to react quickly on any malfunction and locate the source of potential problems.

The PPC Equipment Tester provides function to test the sensor, adapter plate, cables and the signal input of the Master.
