Automated metal detection for safe, compliant plastic packaging

Metal contamination in plastic packaging lines can lead to costly rejects, customer complaints, and compliance issues.

Delta Engineering’s in-line metal detection delivers fast, automated inspection for empty plastic bottles or trays, detecting ferrous and non-ferrous particles without slowing down production. Integrated directly into the conveying flow, it maintains product integrity, improves line efficiency, and protects the customer’s brand reputation.

In-line metal detection

Our integrated metal detection units inspect every container at full production speed, detecting ferrous and non-ferrous particles with high sensitivity. Designed for unstable bottles, they feature 15° transfers, smooth conveying, and full line-control integration to ensure compliance with the strictest hygiene standards.
