Leak Testing for Automotive Components, E-Mobility, and Mobile Energy Systems
The automotive industry is undergoing a transformation: electrification, new drive concepts, stricter quality requirements, and high production volumes demand reliable, automated, and reproducible testing processes. Whether classic vehicle components, e-mobility applications, thermal management, hydrogen systems, or safety-relevant assemblies – leak-tightness is a central factor for function, safety, and service life.
MACEAS develops customized testing systems for automotive and mobility applications. The systems are tailored to component geometry, cycle time, test gas, leak rate, variant diversity, and degree of automation – from semi-automatic test stations to fully integrated end-of-line systems.
Leak Testing in Automotive & Mobility
In vehicles, numerous components must be permanently leak-tight: media-carrying systems, cooling circuits, housings, tanks, valves, battery packs, hydrogen components, and electronic assemblies. Leaks can lead to loss of function, safety risks, complaints, or reduced service life.
Depending on the application, helium vacuum leak testing, helium sniffing, gas bubble detection in a water bath using ultrasound, or other application-specific testing methods are used. Crucial is a testing concept that fits the real production environment and enables stable measurement results with short cycle times.
Typical test objects
- Battery housings, battery packs, and thermal management components
- Cooling plates, heat exchangers, lines, valves, and connections
- Hydrogen pressure vessels, fuel cell components, and H₂ periphery
- Housings, sensors, actuators, and media-carrying assemblies
- Tanks, pumps, filters, fittings, and connecting elements
