Since 2012, Weha-Therm in Hutthurm, Germany, has relied on Softsolution’s quality assurance systems. What began with a smaller camera-based template measurement installation (VirtualDigitizing) has developed into a comprehensive partnership over the years. Today, the company uses three high-performance LineScanners that ensure consistently high quality across Weha-Therm’s production lines.
Since 2016, a LineScanner has been operating on the insulating glass line downstream of the washer. The scanner performs a comprehensive single-pane inspection before the glass is processed further. In addition to surface quality, the LineScanner also checks glass thickness and identifies coatings.
This early inspection ensures that only flawless glass panes proceed to further production. Defective glasses are sorted out before processing into insulating glass units. This saves material, reduces scrap, and prevents costly rework on finished insulating glass units.
In 2019, another LineScanner was installed on the second insulating glass line before assembly / after the washer. The system performs all-in-one glass quality control, inspecting surface defects, dimensions, and other quality-relevant parameters. Since installation, the LineScanner has operated reliably and delivers precise quality data for production.
Integration into the LiSEC line enables automated control without manual intervention. Defects are immediately detected and documented in the data archive.
In 2025, Weha-Therm expanded its quality control by adding a LineScanner White Haze. The system detects white haze on tempered single-pane glass at varying intensities. This reflection-based scanning technology specifically inspects the bottom glass surface and classifies white haze as mild, medium, and strong.
The LineScanner White Haze uses AI-based software that enables precise, consistent evaluation. During production, Weha-Therm can ensure that only glass with acceptable white haze levels is shipped. This prevents claims and strengthens customer trust.
The more than 13-year collaboration between Weha-Therm and Softsolution demonstrates how a partnership relationship contributes to the continuous development of quality assurance. Through the gradual expansion of its systems, Weha-Therm has steadily improved its quality standards and positioned itself as a reliable partner for high-quality glass products.
