Abstract

The present invention generally comprises a method for enhancing the breakdown and removal of a sand mold from a casting formed within the mold to speed up the exposure of the casting to heat treatment temperatures and enhance the breakdown and reclamation of sand from the sand molds. According to the present invention, the method of dislodging a mold from a casting can include placing one or more explosive charges or organic or thermally degradable materials at one or more selected locations within exterior walls of the mold. An additional embodiment includes a method of dislodging a mold from a casting formed within the casting by stimulating the mold with a high energy pulsation. <IMAGE>
