The plastic injection molding process can generate anomalies that are very similar to those that are found in castings and they are revealed and analyzed in much the same way. Computed tomography (CT) imaging makes a great tool for performing first article inspections and can often be used as a substitute for traditional contact measurement inspections. A CT scan produces data that can be directly compared to a CAD model to identify and highlight out-of-tolerance conditions. CT can also provide a quantitative analysis of porosity in the plastic product, and can be used to provide dimensions on both external and internal features.

• Common uses: product quality, metrology and first-article inspection, wall-thickness analysis, porosity analysis, foreign material
• Common products: Plastic housings, electrical connectors, medical device components
