Many foundries prefer chemically bonded sand mold over green sand when it comes to castings with thin-wall sections and complex internal dimensions, yet casting issues can result in costly defects. This presentation addresses chemically bonded sand erosion and surface finish issues for aluminum and cast iron castings. Erosion in chemically bonded sand can occur when molten alloy dislodges grains of sand, resulting in a rough as-cast finish.
