摘要： An injection molding system is disclosed that utilizes a melt channel wherein at least a portion of the melt channel has a noncircular cross-section for balancing shear in a melt stream of moldable material that flows therethrough. The noncircular cross-section of the melt channel portion may be, for e.g., capsule-shaped, extended egg-shaped, oval, teardrop-shaped, or peanut-shaped. A flow splitter is also disclosed that is positioned offset from a central axis of an upstream melt channel to protrude between inlets of respective downstream melt channels, where the upstream melt channel splits into the downstream melt channels, to thereby create a narrower inlet into one of the downstream melt channels and a wider inlet into the other of the downstream melt channels.

摘要： A valve pin bushing assembly for an injection molding apparatus. The assembly includes a bushing body for connection to a manifold, a flexible barrier having a first end that is continuously connected to the bushing body, and a valve pin continuously connected to a second end of the flexible barrier. The valve pin extends through a nozzle in a downstream direction towards a mold gate, wherein the valve pin is movable in an upstream direction and in the downstream direction for opening and closing the mold gate. The flexible barrier seals a channel of molding material from an outside space.
