{{Main article|Full-mold casting}}

Full-mold casting is an evaporative-pattern casting process which is a combination of sand casting and [[lost-foam casting]]. It uses an [[expanded polystyrene]] foam pattern which is then surrounded by sand, much like sand casting. The metal is then poured directly into the mold, which vaporizes the foam upon contact.
