Date Jan. 8, 1996Squeeze casting of high integrity, near net shape castings is performed in a mould cavity defined by cooperating die parts which are movable with respect to each other and have a separation distance which is selected to define a predetermined cavity volume for the cast article. A conduit has a first end connected to an entrance in the lower die part of the mould cavity and a second end connected to a receptacle which contains molten metal. Molten metal is transferred upwardly from the receptacle through the conduit to fill or substantially fill the mould cavity. The entrance to the mould cavity is sealed, and pressure is applied on the die parts to further reduce the cavity volume during solidification of the metal in the mould cavity.
