Surface Quality Castings are generally furnished with unmachined as-cast surfaces, unless otherwise specified. Numbering from left to right, green sand cast parts achieve a 3 or 4, depending on part geometry. Metal type also influences surface quality, since certain metals flow better than others. Most other surface factors are controlled with proper foundry practices. Soundness and Tolerance Soundness of metal components refers to freedom from impurities such as sand inclusions, slag inclusions, macro porosity, and shrinkage.
