Abstract:

A method of serializing a cast part includes providing a mold for a metal casting, with the mold including an inner face partially defining a part cavity; laser engraving a representation of the two-dimensional data matrix into the inner face of the mold; and forming a serialized part by pouring molten metal into the part cavity of the mold, where the molten metal fills the part cavity including the engraved representation of the two-dimensional data matrix. The two-dimensional data matrix being generated by an electronic controller and includes error correcting information and part identifying information.
