Helium leak detectors

  • 26-Aug-2015 01:09 EDT

Helium leak detection systems are helping transmission suppliers improve quality and reduce the cost of producing new automatic transmissions. Kuka Assembly and Test Corp., for example, has developed leak-detection systems that it claims are faster and more reliable than more traditional air-test methods. Kuka now uses Inficon helium-leak detectors to test advanced transmissions such as newer aluminum automatic 9- and 10-speed transmissions. By detecting leaks soon after the original casting takes place, the system reduces cost by eliminating defective castings early in the build process. Air-pressure testing might take days to detect certain types of leaks; helium leak detection takes seconds, the company notes, with a total part-to-part test time of roughly 30-40 sec.
