Metal Sand Casting
Metal sand casting is a casting process where a mold is made from sand. A pattern is used to create a cavity in the sand, which is then held in a flask. Molten metal is poured into the cavity and once it cools and solidifies, the sand mold is broken away to reveal the cast metal part. It can be used with various metals like iron, aluminum, and bronze.
