Device heads towards true zero defect production

A Kistler Instruments product story

Compact all-in-one device incorporates eight signal amplifiers for process optimisation, monitoring and documentation, including an integrated electronics and software package.

Building on its experience of using in-cavity pressure profiles to monitor and control the injection moulding process, Kistler Instruments has developed Como Injection, a system that could help towards true zero defect production.

The compact all-in-one device incorporates eight signal amplifiers for process optimisation, monitoring and documentation, including an integrated electronics and software package.

The integral web server allows set-up and display of process parameters using a standard web browser on a PC or laptop or the optional, dedicated touchscreen monitor.

An Ethernet interface lets process data be communicated to a production planning and control or ERM system and downloaded to any location via the internet.

To simplify installation, it uses a multi-channel connection system based on the single-wire technique to connect to the cavity pressure sensors.

This allows up to eight cavity pressure sensors to be connected to the system using a single cable and plug.

This multi-channel cable technology reduces set-up times and the risk of connection errors.

During a production run, all process data are continuously recorded and can be stored for process analysis and quality assurance monitoring, including the production of relevant documentation.

In addition to production monitoring and control of the injection process based on cavity pressure, Como Injection provides one outputs-valid signal for synchronising with the good and bad part separation system, the handling device or the machine input for external signals.

Eight good and bad part channels can be used to signal to the downstream device whether the active shot complies with the quality requirements (good part) or not (bad part).

These eight channels can also be reconfigured for deployment as real-time outputs to support complex moulding processes.
