Abstract
A plurality of molds are disposed on a rotatable base. The base is rotated to move each of the molds in turn through a pouring station to an article removing station and back to the pouring station. A molten nickel chrome super alloy is poured into each of the molds in turn at the pouring station. The molds are cooled by a flow of cooling fluid. The nickel chrome super alloy articles are removed from the molds at the article removal station. The base may be continuously or intermittently rotated relative to the pouring station. Molten metal may be continuously or intermittently poured at the pouring station.
