Perfectly Sealed Corners Without Rework: CleanCorner Technology

Written by Sarah Hummelsberger | Mar 25, 2026 7:00:49 AM

In glass production, every detail counts. In particular, the quality of sealing in corner areas has long been a challenge: excess material, uneven surfaces, and additional cleaning effort often resulted in manual rework. With the new LiSEC solution, this is now a thing of the past.

THE SOLUTION: CLEANCORNER TECHNOLOGY

LiSEC’s latest sealing system, the SRP‑A sealing robot, is based on the patented CleanCorner technology. A new unit integrated into the sealing head ensures perfect corner quality, allowing finished elements to be removed directly from the machine without any need for operator rework. This is not only a visual improvement, but also a decisive step toward fully automated production lines.

WHY IS THIS IMPORTANT?

Time and cost savings: No manual rework means less effort and higher efficiency.
Clean results: The technology ensures a flawless surface – even in the sensitive corner area.
Automation without compromise: Consistently high quality is essential, especially for lines with robotic unloading. CleanCorner makes this possible.

FURTHER HIGHLIGHTS OF THE NEW MACHINE GENERATION

Optimized guidance of the glass element:

A new suction-axis system stabilizes the glass during the sealing process and improves overall quality.
CleanSeal technology:

The proven CleanSeal system ensures precise material dosing and minimal waste.
Optional automation steps:

Additional modules, such as the label applicator, make the line even more efficient.

Precise application of side labels with the automatic label applicator

The new generation of LiSEC sealing machines not only offers CleanCorner, but also key advantages in terms of standardization:

Faster installation:
The use of standardized components significantly simplifies on-site installation.

Simplified spare parts supply:
Uniform components result in shorter delivery times and reduced complexity.

Proven quality:
Standardization is based on tested components, increasing the reliability of the entire system.

Fazit

With CleanCorner, the new generation of LiSEC sealing machines sets new standards in glass production: perfect corners, less rework, maximum automation, and well‑designed standardization for greater efficiency.
