<p>A sand mold (10) is produced with a blocking device (30, 31) close to the feed channel (22). The feed channel is connected to a feeder (20) of the casting material under pressure, and the mold is filled. The device (30, 31) is moved to block the feed channel before total solidification of the casting, and the mold is rotated through half a revolution to ensure final solidification in a gravity mode.</p> |
