Automatic Leak Detection (2)

On a high-speed production line, a single leaking bottle can shut down operations, contaminate entire batches, and generate significant waste in only seconds. Ensuring that every bottle is completely sealed is therefore critical for maintaining both product quality and production efficiency. This project addresses this challenge by developing a rapid and reliable leakage-detection method tailored for Cosmaline’s bottling line using pressure-decay testing. In this approach, each bottle is subjected to constant internal pressure, and its ability to maintain that pressure is monitored over a short evaluation period. Controlled tests were performed on a set of defective and non-defective bottles to validate the proposed method as a proof of concept for an automated leakage-detection system. The results revealed a striking contrast: non-defective bottles consistently maintained the applied pressure, while defective bottles showed an immediate and significant pressure drop, clearly indicating the presence of a leak. This distinct response confirms that pressure-decay testing is a dependable and easily interpretable indicator of bottle integrity. The project concludes that the method provides a strong foundation for an automated inspection system, and recommends future enhancements aimed at reducing the required testing time, enabling the system to operate even faster and more seamlessly within high-speed industrial environments. Based on these findings, a prototype system was designed and manufactured for future implementation.
