Leak and function testing for the automotive industry
Leak testing is an essential part of the automotive manufacturing process to ensure vehicle safety and reliability. A leak can occur in various systems of a vehicle, e.g., the fuel system, exhaust system, cooling system and brake system. Leaks can lead to problems: loss of power, lower fuel efficiency and even fires. These faulty, leaking components result in recalls, rework, etc., and thus not only cause financial damage to your company but, in the worst case, can pose a health and safety risk to everyone.
As specialists in leak testing for automotive manufacturing who know the specific requirements of the industry, we can help you avoid these risks. In-depth specifications or requirement specifications, which place high demands on the documentation and design of the systems require reliable and suitable solutions for leak testing.
With modular interchangeable tool systems, for example, flexible production is possible without any problems, so that call-off numbers can be accommodated. To meet the demands of the industry, our software provides one hundred percent traceability and high system availability with low maintenance requirements.

Leak testing of automotive components for maximum safety
By carrying out regular leak tests, car manufacturers can detect and correct any problems before they become serious. A leak can occur in different systems of a vehicle, e.g. the fuel system, exhaust system, cooling system and brake system.
There are different methods for leak testing components used in vehicles. One common type of leak test is pressure change measurement , which involves pressurizing a system and measuring the rate of pressure drop. This makes it easy to detect leaks in large-volume parts such as engines, coolant tanks and other components.
Another solution is leak testing with helium/tracer gas. Here, the test gas is introduced into a component, and leaks are detected with the help of specially-made test equipment. This method has the advantage that smaller leak rates can also be reliably detected in larger components, including batteries, airbags or fuel filters.
