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.
LACO engineers provided a flexible solution using our FLEXSTATION helium leak test system along with several custom leak test chambers machined out of aluminum billet. 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 airproof test, occlusion test and functional pressure sensor test.
