FIELD: technological processes.
SUBSTANCE: invention relates to metallurgy. Mold casting system system for casting metal comprises feeder cup (12) fitted on tubular body (14). Tubular body defines through hole passing through it for connection of cavity of feeder cup with cast part and comprises compressible part (26) located between its first (18) and second (22) ends. Cup (12) comprises continuous side wall (16), which defines a cavity for receiving liquid metal during casting. In side wall (16) from the base there is at least one recess (24), wherein second end (22) of the tubular body passes into recess (24) at a fixed depth.
EFFECT: higher quality of casting produced during casting process and elimination of destruction of feeder cup at ramming of molding mixture in casting mold.
