Abstract (en)
[origin: EP0234877A1] A method of making a casting comprising the steps of, at a casting station, feeding molten metal from a primary source (10) of molten metal (11) into a mould cavity (15) through an ingate (49) below the top of the mould cavity, placing the cavity out of feeding relationship with the primary source by changing the orientation of the cavity relative to the force due to gravity to prevent flow of molten metal from the cavity towards the primary source and to permit of flow of metal from a secondary source (42) to the cavity, the cavity being continuously connected to the primary source during said change of orientation, transferring the mould cavity to a cooling station spaced from the casting station and, at the cooling station, permitting molten metal to flow to the cavity from the secondary source whilst the metal in the cavity solidifies.
