Metal Sheet Inspection

Automate Visual Inspection Procs in CTL Line: Detect Defects and measure width and length

In Cut-to-Length (CTL) operations, where metal coils are flattened and cut into sheets, maintaining surface quality and dimensional accuracy is essential. Defects and miscuts can compromise downstream manufacturing and cause significant material loss.

Intelgic’s AI-driven Machine Vision Solution offers real-time inspection of metal sheets in motion, ensuring each plate is defect-free and meets the exact length and width specifications—all without slowing down the production line.

Key Capabilities

Inline Defect Detection

Detect surface anomalies in real time across both top and bottom surfaces.

  • Scratches, dents, pits and pinholes
  • Corrosion and stains
  • Roll marks and surface imperfections

Accurate Dimension Measurement

Precise inline measurement of each sheet with real-time validation.

  • Length and width measurement
  • Real-time validation against specs
  • Alerts on tolerance violations

Sheet Counting & Tracking

Comprehensive plate tracking with quality data for every sheet.

  • Automatic sheet counting
  • Defect tagging per plate
  • Complete dimensional data logging
