In order to call a casting mould with a molten metal, the latter is caused t o flow into through an annular chamber into the shaped cavity of a casting mould, such annular chamber discharging along the entire external circumference of the shaped cavity into the latter. The inflow of molten metal into the annular chamber is interrupt ed by means of a piston, which, being borne inside the annular chamber, is capable of sliding therein. The molten metal is caused to flow across a large flow cross-section, which shortens the filling time even with reduced flow velocity.
