A method and apparatus in the production of metallic castings in which metal in molten state is fed from a heated container to a mold or a smaller container via a pressure pipe, a pressure-generating means and a suction pipe. The temperature of the metal, which is present in the suction pipe, in the pressure-generating means and in the pressure pipe, is controlled by heat-generating means in order to keep the metal at a temperature corresponding to or exceeding its melting point, so that the metal is present in molten state during its passage through the pipes and the pressure-generating means.
