Challenge & Solution

Separator Pinhole & Coating Defect Detection

ChallengeAt high web speeds, traditional visual imaging success rates fall below 60%, with false-positive rates as high as 30%, relying long-term on sampling.

SolutionAn inline AI-AOI solution for high-speed webs reliably catches pinholes and coating defects even at high line speed.

98%Pinhole detection rate (was 70%)

2%Missed detection rate (was 30%)

5%False positive rate (was 30%)
