Casting is a process in which molten metal is poured or injected and allowed to solidify in a suitably shaped mold cavity. During or after cooling, the cast part is removed from the mold and then processed for delivery.

Casting processes and cast-material technologies vary from simple to highly complex. Material and process selection depends on the part's complexity and function, the product's quality specifications, and the projected cost level.

Non-ferrous materials account for the approximately 20% (but growing) portion of castings that are not iron-related. Materials include aluminum, zinc, copper, magnesium, bronze, lead, titanium, and beryllium. These foundrys generally operate on a job or order basis, manufacturing castings for sale to others or for interplant transfer. Industries served include aerospace, transportation, medical and household.
