A transfer system for delivering molten metal against gravity from a pressurized furnace to a mold, comprising: a ceramic lined refractory metal gatebox adapted to sit on or above the furnace, the gatebox having one or more openings at its top for communicating with the mold and having a plurality of metal transfer openings along its bottom; a stalk tube depending from each of the gatebox bottom openings, each stalk tube being effective to extend into at least the upper region of the molten metal within the furnace; a sealing gasket between the stalk tube and gatebox; means for imposing a first fluid pressure on the molten metal in the furnace to gradually force the molten metal up through the stalk tubes into the gatebox to substantially fill same, said stalk tubes promoting a convection circulation of metal between molten metal between the furnace and gatebox to retain the temperature of the molten metal in the gatebox at a difference of no greater than 5°-15°F without the need for external heating; and means for imposing a second fluid pressure on the molten metal in the furnace to quiescently force the molten metal of the substantially filled gatebox into the mold with little or no momentum effect.
