A global supplier of automotive components required a small footprint leak test system with tooling to support a complex part shape and multiple types of tests, including an inner and outer tube leak test, pressure sensor functional test, and a flow/occlusion test. 

We engineered a flexible solution using our FLEXSTATION helium leak test system featuring a custom leak test chamber with custom tooling blocks to accommodate two unique test parts. With chambers featuring minimal test volume and hard interface tooling, the paths made in the aluminum precisely fit the complex shape of the part, reducing dead space and speeding test cycles. The system utilized the helium hard vacuum leak test method with air proof test, occlusion test and functional pressure sensor test.


  • Custom aluminum test chamber designed with two interchangeable tooling blocks that mount to the test part. 
  • FLEXSTATION software configuration to accommodate a variety of test fixture and test sequence options
