For over a decade, Weha-Therm has relied on Softsolution to enhance quality assurance through advanced, automated inspection systems and continuous innovation.

Continuous Development Through Automated Quality Control

Since 2012, Weha-Therm in Hutthurm 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.

LineScanner for Single Pane Inspection on the IG Line

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.

LineScanner for Glass Quality Control Since 2019

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.

LineScanner White Haze – New Technology for Tempered Glass

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.

Satisfaction Across the Board

Johannes Freund of Weha-Therm is extremely satisfied with the LineScanner systems and the collaboration with Softsolution.

“The two LineScanners on the insulating glass lines have delivered reliable quality data for years. The newly installed LineScanner White Haze provides an important addition for the tempering operation and enables objective white haze evaluation,” says the Managing Director of Weha-Therm.

He particularly emphasizes the data archive for all LineScanners. It stores all scan and quality results centrally, enables quick access to historical data, and supports continuous improvement of production processes. As a result, claims have been reduced.

Long-Term Partnership as a Success Factor

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.
