Abstract:
1. An injection molding system comprising; a hot runner manifold that includes an inlet channel for receiving a melt stream of moldable material from a melt source and at least one melt channel for conducting the melt stream of moldable material received from the inlet channel to manifold outlets, each of which is in fluid communication with a hot runner injection molding nozzle, wherein the at least one melt channel includes an upstream melt channel that splits into at least two downstream melt channels and wherein at least one of the upstream melt channel and the at least two downstream melt channels has a noncircular cross-section along substantially the respective lengths thereof, the upstream melt channel has a circular cross-section and the at least two downstream melt channels have a noncircular cross-section along substantially the respective lengths thereof, or the upstream melt channel has a noncircular cross-section along substantially the length thereof and the at least two downstream melt channels have a circular cross-section.
