MANUFACTURING_CHALLENGE
Hyper-connected assembly lines produce thousands of components daily but defect detection relies on static rules and manual inspection
1
Visual inspection bottlenecks
Humans miss micro-defects
2
Data silos
Camera, torque, PLC data separated
3
Root cause analysis delays
Hours to trace defects upstream
4
Over-maintenance
Machines serviced on schedule, not condition
5
No closed feedback loop
Quality data not fed back to design
↓
High scrap rates
→
Warranty claims
→
Rework cost
→
Lost productivity
→
Tens of millions in annual losses
Autonomous Quality Intelligence
Each 1% defect reduction translates into tens of millions of dollars saved annually for OEMs through computer vision, predictive analytics, and GenAI copilots.
