scanned and digitally reconstructed
for accurate reproduction.
2. Material Optimization: By
switching from brass to stainless
steel, the new components offered
significantly improved durability for
continuous operation in demanding
environments.
3. Perfect Fit: The newly manufactured
valve heads met all dimensional and
functional requirements, ensuring

• Lab values could be replicated
• Early-stage PM issues were detected
• Automation and optimization became possible
A few months post-installation, the benefits were clear:
• Reduced broke
• Optimized chemical and energy use
• Improved raw material evaluation
• Fewer claims
ROI was below 6 months! => The system paid itself back
within six months!
Success Story 2:
In June 2021, Nicole Buschmeier visited the Sappi Ehingen
mill for the first time, introducing the KPNB-Net-Work, including
Pixact. The technical manager was highly interested in the
monitoring system for dirt particles. In the pulp and paper industry,
the purity of the raw material is crucial for product quality and
production costs, and Sappi Ehingen was looking for a solution to
