In plastics engineering, high-resolution X-ray technology is used to optimize the casting and spraying process by detecting contraction cavities, blisters, weld lines and cracks, and to analyze flaws. X-ray computed tomography (CT) provides three-dimensional images of object characteristics such as grain-flow patterns and filler distribution as well as of low-contrast defects.
Within the field of plastics engineering, X-ray computed tomography is also used in three-dimensional measurement.
