Patent ID: 7326049

Claim:
An injection molding apparatus, comprising: a manifold including, a cast manifold block, a junction component fixed in the manifold block and having an axial bore with a first end opening to an exterior surface of said manifold block for receiving a flow of melt material, and at least one radial bore in fluid communication with the axial bore and having at least one opening to an outer surface of said junction component, and at least one pipe fixed in the manifold block, wherein said at least one pipe has a first end that engages said junction component at the at least one opening of said radial bore, said junction component and said at least one pipe defining a manifold channel for directing the flow of melt material; wherein the junction component and the at least one pipe are separate pieces that the manifold block has been cast around, and a nozzle defining a nozzle channel in fluid communication with the manifold channel for receiving the flow of melt material through said at least one pipe.
