Kistler has optimized its proven solutions for hot runner control and statistical process control (SPC) in plastic injection molding.

The firmware update for the ComoNeo 7.0 process monitoring system includes new software features that entail improved control of individual hot runner nozzles in multi-cavity molds. The AkvisIO process data management software has also been upgraded, now with an integrated OPC UA connection for injection-molding machines.

Firmware update for the ComoNeo 7.0 process monitoring system

In the revised ComoNeo 7.0, Multiflow 2.0 ensures a consistently high level of quality over a large number of cycles. A newly developed, self-learning algorithm automatically balances the individual filling times for multi-cavity molds during the injection process.

This shortens the filling-time difference so that the individual pressure curves are more precisely aligned, leading to a homogeneous and uniform injection result despite possible fluctuations in the flow rate.

Other new features include additional monitoring options with improved user-friendliness. The new “PREDICT calibration” function lets users adapt the previously trained model to new pressure curves without the need for an extensive new test plan.

ComoNeo 7.0 now also records the pulse and the falling edge of the digital signals in addition to the rising edge. This captures machine sequences better and can also be relevant for statistical evaluations.

Upgraded AkvisIO 7.0 process data management software

The Upgraded AkvisIO 7.0 process data management software consolidates, saves and documents injection molding data from various sources, including ComoNeo. The new software is more user-friendly thanks to its new progress display and detailed import documentation.

As the latest beta feature, the software allows users to integrate injection molding machines as additional data sources via a new Euromap-77 interface for more accurate monitoring. The goal is to uncover long-term trends of correlations between machine data and process parameters and to use those insights to better evaluate optimization potential.
