Abstract
An injection molding apparatus is disclosed having a single level manifold that utilizes a melt splitter. The manifold defines an inlet and a plurality of outlets with at least one upstream melt channel and a plurality of downstream melt channels that are situated between the inlet and the plurality of outlets. The upstream melt channel branches into the plurality of downstream melt channels with the upstream melt channel and each of the downstream melt channels longitudinally extending in the same plane. The melt splitter is at least partially positioned within the upstream melt channel where the upstream melt channel intersects with the plurality of downstream melt channels. The melt splitter divides a melt flow received from the upstream melt channel into substantially equal volumes and then directs each of the substantially equal volumes into a respective one of the plurality of downstream melt channels.
