Abstract
A casting device for counter gravity casting of a light-metal alloy avoids local expansion of the mould cavity. The device includes a pump for conveying molten light metal from a holding furnace through a reservoir via a nozzle to an inlet system in a mould in order fill the mould cavity. The mean cross-sectional area of the reservoir is substantially greater than the mean cross-sectional area of the inlet in the mould. The length of the reservoir constitutes a major portion of the distance between the pump and the mold.
