Mounted after preform sorting inside the blow molding machine, the unit adopts high-quality industrial cameras together with maintenance-free LED lighting to inspect all preform necks. Defects including notches, dimensional deviations, out-of-roundness and scratches that fail quality standards can be reliably detected, preventing defective preforms from proceeding to downstream processes and avoiding production waste.


It detects defects such as black spots, bubbles and contamination on preform bodies and is also equipped with high-quality industrial cameras and maintenance‑free LED lighting.
Compact design for easy integration into blow molders
The inspection modules feature an IP65 protection rating, enabling them to withstand harsh production environments
Customers can flexibly select and install the modules according to actual requirements. They can also be combined with other functional modules (e.g., empty bottle inspection) to meet multi‑functional inspection demands
