PROBLEM TO BE SOLVED: To provide a method and a device for casting the molten metal in an open ended mold cavity, by confining the peripheral outline of the molten metal in the cavity when molten metal is cast into the shape of a final product. SOLUTION: When a body of startup material (70) has been interposed in the cavity (4) between the starter block (60) and a first cross-sectional plane (72) of the cavity transverse the axis (12) thereof, the starter block has commenced reciprocating along the axis, and the body of startup material has commenced reciprocating in tandem with it, through a series of second cross-sectional planes (74), layers (76) of molten metal are successively superimposed on the body of startup material adjacent the first cross-sectional plane of the cavity, and the layers of molten metal sustain a prescribed peripheral outline different from the outline of the cavity.
