Metal Sheet Inspection

Automate Visual Inspection Process

In the aluminum sheet manufacturing process, coloring or coating is a critical final stage that gives the sheet its visual appeal and functional properties. However, this process often introduces surface defects such as stains, color patches, streaks, pinholes, blotches, and coating inconsistencies—which, if undetected, can result in costly quality issues and customer complaints.

Intelgic’s Machine Vision AI solution is engineered to inspect colored or coated aluminum sheets in real time as they move on high-speed lines. Our system ensures that every square inch of the sheet is evaluated for surface defects and color quality—before it is cut, rolled, or shipped.

Challenges in Colored Aluminum Sheet Inspection

Reflective Surfaces

Reflective and glossy finishes make defect detection difficult

Subtle Defects

Haze, gloss variations, and color uniformity issues can go unnoticed

High-Speed Production

10–80 MPM demands real-time, automated inspection

Manual Limitations

Manual inspection is inconsistent and lacks traceability
