Abstract
The present invention relates to a method for casting ferrous or heavy metal articles in vertically parted sand moulds of a mould string plant through an inlet below or aside the mould cavity, by filling the moulds with molten metal by counter-gravity delivery using a source of pressure. The pressure is varied during the filling procedure to steer the flow speed and impact on the mould of the molten metal upon complete filling of the mould cavity is reduced.
