Abstract

Procedure for the desmazarchado of precision castings, characterized in that the cooled molds are subjected after casting to vibrations that eliminate in a known manner the refractory shell of the mold and because by varying the frequency of these vibrations, the cluster pieces causing a break in the metal at the maximum throttle point of the casting inlet.
