(54) Method and apparatus for pulsed pressure molding


(57) Method and apparatus for creating a molded product by first liquefying a metal in a crucible disposed in a crucible chamber and then applying a differential pressure level to the liquefied metal so as to force the liquefied metal into a mold. Once the liquefied metal is drawn into the mold, the pressure of the liquefied metal in the mold is raised to a solidification pressure in oscillating pressure steps. Once the pressure is raised to the solidification pressure, the liquefied metal is allowed to solidify.
