ABSTRACT:
A centrifugal casting apparatus for dentistry comprises a rotating member or platform for the mold having a mold disposed on one side thereof, a rotating member for the crucible movably positioned at the center of revolution of the said rotating member for the mold and provided with a crucible and a melting means, and a driving mechanism therefor, whereby metal for dentistry uses charged into the crucible is heated to be molten, while the mold is caused to rotate about the periphery of the crucible by means of the rotating member for the mold, and, after melting of the metal for dentistry uses is completed, the rotating member for the crucible is brought into engagement with the rotating member for the mold for rotation therewith where the metal in the molten state is cast from the crucible into the mold through impact force produced upon transmission of rotation as well as centrifugal force after initiation of rotation.
