The Advantage
The fully automatic Air Leak Test Machine is designed to test the batteries for leakage of the second cover after the heat-sealing machine. This is done by pressurizing the vent holes with overpressure which is then compared with a leak tester at the specified pressure drop rate. The batteries arriving on the conveying system of the machine, enter the automatic testing device separately and are accurately positioned and fixed under the probe. The probe is pressed onto the hole of the battery cover and the battery is pressurized with overpressure. Over a pre-programmed period the constancy of the pressure is then measured within a pre-programmed tolerance zone. Should the tolerance zone be exceeded a visual or audible signal serves as a warning of the defective battery. The measured values of different types of batteries are pre-stored.

A fully automatic air leak test machine checks lead-acid batteries for leaks in the second cover after heat sealing. The battery enters the machine on a conveyor, is automatically positioned under the probe, and overpressure is applied to the ventilation holes. Any pressure drop within the programmed test duration triggers a visual or audible signal, and the defective battery is automatically sorted out via a reject table. No manual handling is required during the test cycle.
The machine features a three-dimensional test stroke that accommodates all common sealed cover types, including standard automotive, truck, and industrial lead-acid battery covers. Short change-over times between battery formats make it suitable for production lines running multiple battery types. The fully automatic process eliminates operator involvement during testing, ensuring consistent results across all formats and high throughput
Yes. The CMWTEC fully automatic air leak test machine is designed for seamless integration into battery finishing lines. It can be combined with the High Rate Discharge Test machine, the High Voltage Leakage Test machine, and other end-of-line modules. A data interface allows test results to be logged and shared across the line for full production traceability.
