Abstract
Surface finish is an integral part of casting quality specifications. Rough internal surface finishes on castings can cause the loss of efficiency for both fluids and high-velocity gasses, and such is the case for turbocharger and intake manifold components. The University of Northern Iowa has been investigating mold material characteristics that affect surface smoothness for castings. The research was conducted on aluminum castings but has applications and relevance in ferrous alloys that do not exhibit defects such as penetration or fused sand defects. The study investigates the influence of molding media characteristics such as sand fineness, material type, and refractory coating selection. The goal of the project was to accomplish investment casting surface finishes in sand cast parts.
