I. Equipment Overview
Project Title: Filled Product Leakage Detection System
Inspection Scope: Designed to detect leakage issues in filled products, including missing or excessive gaskets, product seepage, and bulging cans.
Maximum Throughput: Up to 1,200 cans per minute.
Compatible Containers: Applicable to cans, three-piece cans, glass bottles, metal caps, and other flat, magnetically responsive caps (refer to illustration below).
II. Detection Principle
The system employs electromagnetic pulse (EMP) technology, which generates an instantaneous, directional pulse. When this pulse impacts the container lid, the induced magnetic field causes the lid to vibrate, producing an acoustic response. A built-in acoustic sensor within the probe captures this response and sends it to the processing unit for analysis. Because of the pressure difference inside and outside the container, products with leaks exhibit distinct acoustic characteristics compared to properly sealed products. This principle enables reliable and accurate sealing integrity inspection.

2. Use surface scanning technology to continuously scan the upper surface of the glass bottle cap. If the sealing is not good or the internal pressure of the bottle is abnormal, it will cause a sudden change in the glass bottle cap, thereby judging whether the sealing (or pressure) of the cap is qualified;

Detection accuracy:
serial number
| Test Items | Testing Conditions and Accuracy | Rejection rate
| False kick rate
|
1 | Leakage test | -- | -- | < 0.03% |
1.1 | No lid | No screw cap | >99.99% | |
1.2 | No gasket test | Missing rubber gasket | >99.9% | |
1.3 | Double gasket test | Double rubber gasket | >99.93% | |
1.4 | Air leak test | Product leakage | >99.99% | |
1.5 | Expansion cans and other special-shaped cans | >99.9% |
Note: Rapid temperature changes will affect the detection results and cause false rejections.
V. Installation Requirements
This equipment is installed on a horizontal, single-row conveyor chain. It consists of two components: detection and rejection. The conveyor chain must be at least 1.5 meters long, preferably longer. Ensure the chain plate remains stable during conveying, and the equipment must be installed after the cooler for inspection. (Important)
Installation location
1. The lid material must be magnetic and must be from the same batch during production. Mixing lids from multiple batches may reduce detection effectiveness.
2. Power supply: 220V, 50Hz AC, with a total power draw of less than 120W. If you are using a different voltage standard in a foreign country, please inform us in advance.
3. External compressed air is required for rejection, with a minimum pressure of 4 bar and a maximum pressure of 12 bar.
