Helium leak testing for automotive & EV parts
Production helium leak test systems for EV battery packs, cooling plates, AC hoses and lines, and fuel system components.
EV battery enclosures and coolant circuits must stay sealed for the life of the vehicle, and AC and fuel parts face tight emission limits. We build helium test stations that fit your line's takt time, with fixtures for each variant and data that ties every result to a part serial number.
Key features
- Vacuum chamber, accumulation or sniffer methods to suit the part
- Multi-part or multi-station layouts for production rates
- Barcode / QR scanning linking results to serial numbers
- Quick-change fixtures for model variants
- Optional helium recovery for high-volume lines
- Pressure cycling, thermal cycling and functional test rigs also available

Questions about this machine
Can you integrate with our line PLC and MES?
Yes. We exchange start, result and serial-number signals with your line and can push results to your MES or a database.
Do you also make test rigs other than leak testers?
Yes. We build pressure cycling, thermal cycling and functional test equipment for automotive parts.
