Abstract: An offset mold process deflects a mold assembly being conveyed along a first path laterally of that path into engagement with a nozzle using a shuttle car. Molten metal is pumped into the mold assembly, which is either a cope and drag mold or a lost foam mold, from below the molded part to eliminate eddy currents which can create incongruities in the molded part. One method of flow cutoff involves movement of a first mold component relative to the bottom board cuts off the flow of molten metal and locks the mold fill in the mold assembly. A second method of flow shutoff usable in the lost foam process involves the engagement of a flow cutoff plunger to cut the flow stream once filling the mold has been completed. In both the cope and drag and lost foam apparatuses, withdrawal of the shuttle car enables molten metal in the feed line to drain into a catch ladle obviating the need to burn embedded sand from the scrap prior to its recycling into the melt.
