A vacuum casting machine comprising

• a melting chamber with an opening for pouring metal;
• a vessel for melting metal disposed in said melting chamber;
• heaters for melting metal disposed in said melting chamber;
• a first vacuum seal closing said opening for pouring metal;
• a plurality of casting molds for receiving the melted metal;
• a plurality of mold chambers each having one casting mold disposed therein, each mold chamber having a mold chamber opening for pouring the metal into its casting mold;
• a plurality of second vacuum seals, each of said mold chambers having one of said second vacuum seals for closing the mold chamber opening for pouring the metal into its casting mold;
• a rotary table accommodating around its circumference said plurality of mold chambers with associated molds;
• a self-contained drive of said rotary table operatively associated with said rotary table, said rotary table serving the purpose of registering, in turning, each of the mold chamber openings for pouring metal in said mold chambers containing the molds with said opening for pouring metal in said melting chamber;
• a vacuum sealing means serving to couple said first vacuum seal with each of said second vacuum seals in a vacuum-tight fashion during the process of pouring the metal into said casting molds;
• a system for evacuating said melting chamber and associated mold chamber with mold;
• an additional vacuum system disposed away from said rotary table for evacuating said mold chambers prior to connection with said melting chamber;
• a sealed rotatable connecting means for connecting said additional vacuum system to all of said mold chambers on said rotary table, and
• a support means for supporting said melting chamber and said rotary table.
