A process for reconditioning an ingot mold of the type including an elongated cavity area having some predetermined volume and at least one open end for purposes of extending the useful life thereof. In accordance with the reconditioning process, a short portion of the mold length is cut-off or machined away at a mold cavity open end to eliminate the usual mold damage which typically occurs at that area after a number of separate casts. The cut-off is effected so that the mold cavity will have some new volume comprising some predetermined reduction of the original volume. This second volume is calculated such that ingots then cast from the reconditioned mold and thereafter processed may be cut into a lesser number of bars having substantially the same size and volume characteristics as those bars cut from ingots cast in the original mold. In some cases, it may be desirable to also machine at least the mold cavity side walls so that the original surface conditions and dimensional relationships are substantially assumed.
