Sand inclusion is very common. It is expected in small quantities at surface depths for all sand castings. However, too much sand inclusion can ruin a casting. In this defect, sand from the mold gets trapped in the metal. If there is a lot of sand inclusion at the surface, it might indicate the need for a mold wash, or a different molding system.
