Abstract: A method and system of inspecting pre-molded parts comprising sealant material are disclosed. The method includes directing a micro-focused X-ray beam through a pre-molded sealant part comprising a sealant material to produce a phase-shifted refracted X-ray beam, and detecting the refracted X-ray beam with at least one phase contrast imaging X-ray detector to produce an image of the sealant material. The system includes at least one X-ray source structured and arranged to direct a micro-focused X-ray beam through a pre-molded sealant part comprising a sealant material to produce a phase-shifted refracted X-ray beam, and at least one phase contrast imaging X-ray detector structured and arranged to detect the refracted X-ray beam to produce an image of the sealant material.
