Common Defects in Various Casting Processes

Abstract

The International Committee of Foundry Technical Associations has identified seven basic categories of casting defects: metallic projections, cavities, discontinuities, defective surfaces, incomplete casting, incorrect dimension, and inclusions or structural anomalies. This article presents some of the common defects in each of the seven categories in a table. It also discusses select case studies relevant to inclusions, cavities (gas porosity, shrinkage), and discontinuities (hot tearing, cold shut).
