Abstract: A mold assembly cell for sand mold production comprising a turntable wherein sand cores and other mold parts (which together cooperate to define the casting cavity of the sand mold) are automatically and progressively assembled following a sequential pre-programmed schedule by programmable robots located in proximal relationship with the turntable and a core shooting machine. The assembly turntable rotates clockwise or counterclockwise to permit placement of progressively more-complete mold packages in each of at least three assembly stations to allow the robots to reach the molds being assembled at different angles for simultaneously setting the sand cores and other parts of the mold according to said pre-programmed assembly schedule. Also a mold assembly line comprising a plurality of the foregoing assembly cells to form sand molds for casting complex-geometry aluminum parts, such as aluminum engine blocks and cylinder heads, with greater flexibility, efficiency and productivity.

Abstract: A method for the production of castings which are permanently provided with readable information. An identification element, which has an information surface, provided with information, and a casting surface which is assigned to the casting and also provided with information, is arranged on a casting mould surface assigned to a mould cavity of a casting mould so that the information surface is covered, while the casting surface is exposed in the mould cavity. A metal melt is poured into the mould, so that, during casting or solidification of the metal melt, a firmly bonded, form-fit or force-fit connection of the identification element to the casting is produced. The information on the casting surface is reproduced in the manner of a stamp on surface of the casting. The casting is then removed from the mould and fettled.
