ABSTRACT:
A manifold assembly for supplying plastic material from a plastic source to a mold assembly in an injection molding machine includes a flexible manifold having an interior conduit connected between the plastic source and the mold assembly. The flexible manifold is configured to define an input connector, a first curved segment attached to the input connector, a second curved segment, an output connector attaching the second curved segment to the mold assembly, and an intermediary segment connecting the first and second curved segments. This provides the flexible manifold with a generally S-shaped configuration that flexes with temperature changes to maintain a substantially constant positioning between the input connector and the output connector, preventing thermally induced movement of the mold assembly with respect to the input connector as heated plastic is injected through the conduit.
