Metal castings\u00a0are usually\u00a0inspected by normal X-ray images but the enhanced contrast of X-ray CT allows clear identification of the location, type and potential effects\u00a0of defects without any doubt.<\/p>\n
The example here was a vehicle Cam cover, the images illustrate the largest defects, and for potential clients interested in this inspection service\u00a0we can provide for this example the\u00a0generated CAD file of the surface and the internal defects (included in the CAD file with the internal and external surfaces of the object). We can also provide the image stack of slice images, which is typically used for self-diagnosis of defect areas by the inspection engineer. The scan, CAD file\u00a0and slice image stack was made in 1 hour.<\/p>\n
