Optical Quality Control

 

IN-LINE QUALITY CONTROL 
FOR CONCRETE BLOCKS & PAVERS

 

The HESS Inline QC is a fully automated, non-contact, real-time quality control system—operating inline on the wet side without interrupting the production flow. It inspects every production batch using surface inspection and immediately displays defect images, key metrics, and trends. This allows operating personnel to respond immediately—for example, by adjusting the mixing ratio or machine settings.

Integration & Analysis

The analysis runs seamlessly within the familiar machine visualization interface; in addition, a display unit can show all relevant production metrics and error patterns “at a glance.” Comprehensive statistics and trend analyses support data-driven decisions and help reduce the scrap rate and maintain consistent quality.

What else is possible

When used in combination with a weighing station, it is possible to determine not only height and volume but also density. Defects, colors, and grain sizes of the stone surface are recorded and made available for analysis.

HIGHLIGHTS
 

  • Real-time in line inspection: contactless, fully automatic, no production stop, directly on the wet side.
  • Instant feedback for operators: defect images, KPIs and trends support fast corrective actions in mix and machine settings. 
  • Integration & evaluation: displayed within the familiar machine visualization; key production figures and defect visuals “at a glance”. 
  • Consistent quality, less scrap: statistics and trend analyses support data-driven process optimization.

QUALITY AT LINE SPEED

FULL-SURFACE INSPECTION

The system scans each layer across the entire 
width and length, covering the full product surface,
including edges and corners.

 

AI-SUPPORTED DETECTION

Advanced algorithms differentiate real surface defects from harmless contamination, ensuring reliable classification for every block and paver.

REAL-TIME VISUALIZATION

Height and color deviations are displayed instantly through color maps, enabling operators to react immediately and maintain consistent production quality.
