Sample-PreWatcher

The system offers a high-precision preform inspection inline behind the injection molding machine or offline in a quality laboratory. Especially complex quality characteristics are monitored by the turnkey system.

Comprehensive inspection solution for your preforms

The Sample-PreWatcher inspects all aspects of the preform. It checks batches for a large number of defect criteria – down to the last detail. The system stands out by its precise and extensive measurement and inspection. You can check the quality of your preforms as a part of regular production monitoring or directly after a product change. Within just a few minutes, you receive cavity-correlated information about weight, dimensions, color, cosmetic and other defects for a full shot of preforms. You will make quality decisions many times faster than relying on manual measurements.

The system offers you the best ratio of inspection scope to inspection speed. As a laboratory system, it provides your quality team with fast and reproducible preform monitoring of complex quality features while being easy to operate. But it can also be used to inspect batches of preforms directly behind the injection molding machine.

Data analysis for overall production insights

In order to make decisions easier and faster, the collected data is visually presented within comprehensive statistics and condensed into trends. All information can be transmitted via interfaces to analysis software (for example IntraVisualizer) for further evaluation. This allows you to get excellent insights to monitor and improve the production process.

Strengthen your customers’ trust in your products by always delivering the best possible quality. The more data you have about your production, the more confident you can be about the quality of a batch or a delivery.

    Weight

    • High precision weight measurement

  • The preforms can be transparent, translucent or opaque. They should have a diameter of 20 - 45 mm, a height of 70 - 157 mm, and a weight of up 100 g. If these dimensions do not fit to your preforms, please contact us to find an individual solution for you.

  • Yes, of course. The more data you have on your production, the more confident you can be about the quality of a batch or a delivery. All data is available for direct communication to your ERP or CRM system.

  • INTRAVIS offers turnkey systems, worldwide support and training courses as well as comprehensive printed and digital information material for every single system. After the purchase of the system, INTRAVIS does not leave you alone with your new vision system. Moreover, service contracts offer worldwide support and service, even within 24 hours.
