Advanced Void and Lump Detection Systems for High Speed Gypsum Board Lines

Vision Engineering, Inc. proudly introduces a fully automatic non-destructive void detection and quantification system for gypsum wallboard. Utilizing state-of-the-art infrared cameras and high speed image processors, voids and lumps are automatically located, sized, and counted. These systems (patent pending) provide 100% inspection at rates up to 600 feet per minute.






Non-Destructive Void Detection System



Gypsum Board Void Detection – Features and Benefits

Lump and Hot Spot Detection – VEI’s systems can also optionally detect lumps and hot spots. Lump detection can help provide early warnings when the slurry is not being properly mixed.

Data Logging – All data can be logged to text files, local databases or remote databases. Utilities are also available to provide user defined formatting and batch uploads.

Remote Administration – System fully supports most available remote access software packages including modem, network, and internet based packages.



Charting of voids per minute for the whole board and each of the five user-defined zones.


Real-Time 100% InspectionImages are displayed real-time with all detected voids highlighted. The voids are classified according to size and location. Each minute, totals are calculated and added to an onscreen graph showing the frequency of voids over the last four hours. This data provides a visual reference for the operator to quickly determine recent and/or present board quality. This data also helps determine when adjustments are needed on the wet-end. Detecting voids sooner, and making adjustments when needed results in less wasted product and reduced chance of sending bad product out to the customer.

Uses infrared technology to detect voids and lumps.
Groups voids and lumps into three user defined categories.
System counts voids and lumps in five user-defined zones.
