Cavity Pressure Measurement with q-switch

The aim of measuring mould cavity pressure is to improve cost-effectiveness by reducing the costs of manual post-production checks, shortening set-up times and minimising scrap.

Process deviations can be detected at an early stage, allowing corrective action to be taken before defective parts are produced or incompletely filled parts are delivered to the customer.

Another application is the quick and safe transfer of a mould from one machine to another without the need for time-consuming revalidation.

As the internal mould pressure provides a comprehensive description of the production conditions of the injection-moulded part, it offers insight into the mould cavities – independent of individual machine configurations and parameters.

The internal pressure profile of each part is therefore as unique as a fingerprint.

Our high-performance system for measuring internal mould pressure monitors moulded part quality and provides the operator with precise information for process optimisation.

In the event of viscosity fluctuations in the material, the system detects the ideal switching point and sends a signal to the machine. The selection of channels and the pressure level can be freely configured. This makes the process significantly more stable, as the system can detect and compensate for variations in filling caused by viscosity fluctuations.

All tool-related data is stored in the built-in memory module directly on the tool and is therefore immediately available when changing machines.

The system guides the user through the steps involved in setting up the process. The operator is intuitively guided through each stage until reference curves, tolerances and switching pressures have been defined.

As a result, the learning curve for operating the system is extremely short.
