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.

Brass is an alloy composed of copper and zinc. Brass is stronger than copper and has a more yellow color and will tarnish when exposed to the air if not coated with a clear protective coating.
