Abstract: When casting metal articles in a mould by forcing molten metal upwardly through a filling tube by gas pressure in a closed chamber, the datum level just below that of a connector connecting the filling tube to the mould is registered by a level sensor in a sensing tube while the latter's upper end is connected to atmosphere through a vent tube. At the same moment, the pressure is measured by a pressure sensor and recorded by a control unit and maintained constant by the latter after the emptying of the sensing tube, by connecting its upper end to the chamber through an equalizing tube, until the pressure is increased to fill the mould according to a predetermined function of time programmed into the control unit. The starting point for the filling of all moulds in succession is the same, regardless of the amount of metal in the supply unit.
