Molder Pours Metal into Cast

Molders, also known as foundry mold and coremakers, form sand molds for use in the production of metal castings. This production method, known as sand casting, requires knowledge of the properties of metals and sand mixtures, pattern shapes, and pouring procedures. Implementing a two-part box called a flask, molders pack specially prepared sand mix around a pattern of the object that is to be cast. The pattern is then removed and molten metal is poured into the cavity where it solidifies and forms the casting. Approximately 12,860 foundry mold and coremakers are employed in the United States.
