Water leak test systems · Rain test
Leak testing for vehicles, components and machines. Individually developed.
As a builder of bespoke machines, we develop, plan and build test systems that reliably reveal leaks – for cars, commercial vehicles, trains, buses and motorhomes as well as for electrical components, individual assemblies and machines.

How our leak testing works
A look at our test system in action.
Our system concepts
In-line integration, variable system, audit system, mobile system and long-term water test – five basic directions that serve as a starting point for your individual solution, not a fixed range.

In-line integration
Integrated directly into your production line, for 100% inspection of every vehicle produced.



Mobile system
Can be used at any location – suitable for workshops, trade fairs and changing sites.
Long-term water test
For tests lasting hours rather than minutes, when seals and bonded joints have to hold under continuous load.
Software
Rain Test Web: testing goes digital
Control the system from a tablet or PC, register vehicles by barcode, record leak points with a photo and pass the test history to your ERP system.
Need a different bespoke machine?
AKS GmbH also builds bespoke machines for other tasks. You can find the full range of services at aksgmbh.de.
Trusted across many industries
Cars, buses, rail vehicles, motorhomes and e-mobility, plus electrical components, assemblies and machines – our systems are in use at manufacturers and suppliers in a wide range of industries.
