Abstract
A counter-gravity casting method and apparatus in which the mold is held stationary and the crucible is moved generally laterally from a melt chamber to a fill chamber positioned below the mold with respect to gravity. A casting chamber is located generally above the fill chamber with respect to gravity. The method and apparatus utilize separate chambers for melting and casting in which the pressure in each chamber can be varied relative to each other in order to introduce molten metal into the mold.
