Complete soap bar inspection in one pass
Real-World Use Cases
How soap manufacturers achieve consistent quality with Unicus Vision systems
Embossing & Logo Verification
A luxury soap brand needed to verify intricate embossed logos and text on every bar while maintaining high-speed production of 400 bars/minute.
- 3D profilometry for embossing depth verification
- High-contrast imaging for logo clarity
- AI-powered defect classification (chip vs. scratch)
- Real-time rejection of sub-standard bars
High-Speed Surface Inspection
A large-scale manufacturer required detection of surface defects (cracks, pits, discoloration) on soap bars moving at 600 units/minute in humid conditions.
- IP69K-rated cameras for washdown environments
- Polarized lighting to eliminate soap glare
- Multi-angle imaging for 360° coverage
- Edge computing for sub-30ms decision time
Wrapper & Carton Quality Control
A producer needed to verify wrapper alignment, seal integrity, and carton labeling on final packaging while tracking batch codes for traceability.
- Seal integrity verification via thermal imaging
- Wrapper position & wrinkle detection
- OCR verification of batch/expiry codes
- Integration with MES for full traceability
