Ensuring product integrity
through automated inspection and testing

In high-speed rigid plastic packaging production and filling operations, even the smallest defect can lead to major waste, recalls, or safety risks. Manual inspection is slow and inconsistent. Modern packaging lines demand more reliable control.

Delta Engineering’s automated quality control systems for empty rigid plastic bottles, containers, and thermoformed parts combine leak testing, metal detection, checkweighing, and vision inspection in one seamless process. Each system guarantees traceable, repeatable results that protect product integrity, minimize waste, and maintain full compliance with industry standards.

Leak testing

Detect micro-cracks or leaks at full production speed with Delta Engineering’s non-destructive leak testers. Accurate and repeatable measurements ensure every bottle or container meets your tightest quality standards.

In-line metal detection

Inspect every type of plastic product or packaging for ferrous and non-ferrous contamination. Integrated into the line, detectors identify and automatically reject contaminated products to maintain product safety and prevent machine issues.

Check weighing

Guarantee weight consistency at high throughput. Our check weighing systems automatically reject out-of-tolerance products, ensuring compliance and optimizing material use through feedback to the blow molder.

Vision systems

Together with our partners, we provide advanced vision systems that verify shape, color, label, and print quality in real time. Integrated with Delta’s automation, these cameras ensure visual perfection and reduce manual inspection costs.
