(Marposs: Auburn Hills, Michigan)-- Marposs, a world leader in measurement, inspection, and test technologies, announces the availability of noncontact machine-vision measuring systems able to detect the presence of defects such as porosity, scratches, and depressions on the sealing surfaces of castings. These systems can be used to inspect any kind of housing, from the engine block of a traditional combustion engine to the housing of electric drive units (EDU) for electric vehicles.

Generally speaking, traditional leak testing is used to verify water, oil, fuel, and other circuits on cast parts but isn’t capable of validating sealing surfaces where gaskets must be coupled with other part surfaces. Casting defects can cause leaks that compromise the proper functioning of the component and jeopardize the life of the end product. An irregular mating surface will affect the sealing of the gasket to the casting, allowing fluids to leak into the channels.
