Sand cores can be produced using many of the same methods as sand molds: as molds are shaped by a pattern, sand cores are shaped by a core-box; they are similar to a die and can be made of wood, plastic, or metal. The core-boxes can also contain multiple cavities to produce several identical cores.

Molding is a multistep process that will form a cast around the pattern using molding sand. In casting, a mold is contained in a frame called a flask. Green sand, or molding sand, is packed into the flask around the pattern. This is known as metal sand casting. Once the sand is packed tight, the pattern can be removed and the cast will remain.
