Automated visual quality control to detect defects before they disrupt production

Visual defects such as scratches, deformation, contamination, ovality, or finish imperfections can pass unnoticed in fast-moving production lines. Manual inspection is subjective, inconsistent, and impossible at high speed.

Delta Engineering integrates advanced in-line vision systems from trusted partners, providing 100% visual inspection of plastic bottles and containers. Mounted directly in the downstream flow, these systems detect critical defects early, ensure consistent quality, and prevent defective products from reaching customers or causing downstream stoppages.

Optical inspection systems

We combine our specialized bottle handling expertise with industry-leading vision inspection technology. By ensuring correct and stable bottle presentation, we enable vision systems to operate at their highest performance level, reliably detecting visual defects, dimensional variations, finish defects, contamination, and deformation. Fully automated, recipe-driven inspection ensures consistent quality, fast changeovers, and accurate rejection of faulty products.
