Leak testing machines
Air-decay and pressure-decay leak testers built around the sealing fixture — the part of the system that decides whether your results are trustworthy — with master-part validation and results stored per component.
At a glance
- Methods
- Air decay, pressure decay, mass flow, differential
- Fixturing
- Custom sealing nests and quick connectors
- Validation
- Master part with calibrated leak; repeatability study
- Data
- Serial-wise results with curves and reports
- Lead time
- Indicative 8–14 weeks from design freeze
Overview
Leak Testing Machines built to your application
Most leak-test problems in production are not instrument problems. They are sealing problems, temperature problems and fixture problems: a nest that deforms the part, a seal that relaxes, or air that has not stabilised before measurement begins.
We design the fixture and the test parameters together, validate with master parts including a calibrated leak, and hand over a bench that produces the same answer on the third shift as it did at FAT.
Variants
Types of leak testing machines we build
Air-decay leak tester
Standard method for castings, housings, valves and enclosures.
Pressure-decay bench
Higher pressures for pressure-carrying components.
Multi-station leak tester
Several parts tested in parallel to meet takt.
Battery enclosure leak tester
Large-volume sealing for EV packs and trays.
Specification
Technical specification
Typical build parameters. Final specifications are fixed with you at design freeze.

|---|---|
| Sealing | Custom nests, expanding plugs, O-ring faces, pneumatic sealing cylinders |
| Cycle | Fill, stabilise, test and exhaust times set from part volume and limit |
| Validation | Master good and master leak parts, gauge repeatability study |
| Data | Result, decay curve and parameters per serial number; CSV/SQL/MES export |
| Options | Reject lock, marking after pass, water-bath station for trouble-shooting, multi-cavity testing |

Leak Testing Machines: common questions
What leak rate can you test to?
It depends on part volume, test pressure and cycle time. We select the method and instrument from your allowed leak rate and confirm capability with a calibrated master leak.
Why do we get false rejects?
Usually sealing, temperature difference between part and test air, or a stabilisation time that is too short. All three are addressed in the fixture and parameter design.
Can the tester stop untested parts moving on?
Yes — with interlocks, reject lock bins and marking after pass, so an untested or failed part cannot reach dispatch.
