Abstract
An improved melt distribution system and method is provided for a multi-level stack mold having three or more moving platens. The injection machine communicates with a bifurcated sprue bar for providing pressurized melt through the first moving platen to a central distribution manifold in the second moving platen. From the central distribution manifold, the flow of pressurized melt is distributed to the first and third platens for transfer to a plurality of mold cavities.
