A mold casting process comprises, after pouring of a molten metal into a mold, rapidly cooling that surface layer of a cast product which is in contact with a mold, and releasing the resulting product from the mold when the surface layer thereof has been converted into a shell-like solidified layer. Such process is used for casting a mechanical part blank and apparatus for carrying out the process is provided.

An iron-base article such as a camshaft has a remelted layer of high wear resistance on a cam surface, for example. To make such an iron-base article, molten metal is poured into a mold with a chill set therein to cast an iron-base article having a chilled region formed in contact with said chill. Then, metal powder which provides wear resistance upon being mixed is added to at least a portion of said chilled region. A high level of energy is applied to the portion of the chilled region to heat and remelt the same, and the remelted portion is thereafter cooled to form a remelted layer therein.
