ABSTRACT:
A melt transfer device for an injection molding apparatus includes a first shut off valve coupled to a first nozzle having a first melt channel. The first melt channel delivers a melt stream of moldable material to a second melt channel of a second nozzle, which is movable relative to the first nozzle. A second shut off valve is coupled to the second nozzle. The first shut off valve and the second shut off valve are retractable to open a melt transfer channel of the melt transfer device to allow melt to flow between the first melt channel and the second melt channel.
