Case Studies

Customer Success

Case 1: Japanese Auto Parts Supplier (China Factory)

Parts: M6–M12 bolts, 15 varieties
Challenge: Manual visual inspection of scratches/dents reaching its limit. Needed automation but Keyence was too expensive.
Solution: AI-powered optical sorter + 5MP camera (¥180K CNY)
Result: 400 parts/min, 99.2% defect detection rate. ROI in 8 months.

Case 2: Electronic Connector Manufacturer (China)

Parts: Contact pins φ0.8mm × 12mm
Challenge: 100% inspection of micro-bending, plating defects, and foreign particles.
Solution: High-magnification optical sorter + AI classification (¥250K CNY)
Result: Replaced 3 human inspectors with 1 machine. 70% reduction in customer complaints.
