Customer Request

Our customer produces filters in various designs in a 3-shift operation. Quality control was previously carried out using a rule-based camera system. However, due to the diversity of production, the existing camera system had to be recalibrated daily in order to limit the pseudo reject rate. Despite the regular recalibration of the camera system, the old camera control led to a pseudo reject rate of up to 80%, which in turn led to high scrap / re-sorting costs.


With the introduction of Maddox AI, the inspection system only needs to be recalibrated / retrained in a few cases and the average pseudo reject rate has been reduced by over 90%. Defective filters are now reliably rejected, while OK filters are reliably classified as OK even with different production batches.

With Maddox AI

The existing inspection system had to be recalibrated several times a day.

Das Inspektionssystem muss dank der Maddox AI Software nicht mehr nachkalibriert werden und kann auch mit unterschiedlichen Produkttypen zuverlässig umgehen.

Depending on the product type / batch, up to 80% of the filters were classified as NOK, although the majority of these were OK parts.

Thanks to the increased precision of the Maddox AI inspection system, the pseudo reject rate has been reduced by around 90%.

New product types had to be laboriously stored individually in the inspection software.

New filter types are automatically and reliably inspected by the Maddox AI software.
