Leak detection system for plastic containers
Ensure product integrity and prevent costly recalls with this advanced system that detects even the smallest leaks in plastic containers, safeguarding contents and maintaining packaging stability throughout high-speed production lines.

The HEUFT Squeezer II from HEUFT SYSTEMTECHNIK is a cutting-edge solution designed for in-line detection of leaks and closure faults in plastic containers across the beverage, food, and pharmaceutical industries. This highly automated system employs a flexible leakage check mechanism based on the sophisticated HEUFTSPECTRUM II platform, ensuring reliable protection of microbiological purity in liquid products. By using precise pressure measurement and fill level detection, it identifies defects in PET, HDPE, and PE containers, efficiently removing compromised items from the production line.
The HEUFT Squeezer II seamlessly integrates into your existing processes, providing continuous, high-speed inspection with an optional 360° closure inspection capability for comprehensive coverage. Adaptable and modular, it supports brand and program changes seamlessly, minimizing downtime and manual intervention. This system incorporates various technologies for closure detection, fill level analysis, and image processing to maximize fault detection accuracy.
Energy-efficient with features like servo-controlled belt drives and real-time image processing enhanced by artificial intelligence, the system reduces false rejection rates and optimizes line efficiency. Its hygienic design facilitates easy cleaning, while network connectivity ensures optimal integration into modern production environments, supporting remote maintenance and data acquisition. Customizable detection paths and pressure analysis options make it a versatile tool tailored to meet specific industry needs.
