Abstract: A nozzle for an injection molding machine with a common nozzle outlet chamber to control the injection of at least two plasticized plastic components in a mold, where each plastic component is produced in a separate plasticizing unit and each such unit is connected by the shortest path to at least one separate nozzle inlet which in turn is connected within the nozzle by means of a separate channel to the common nozzle outlet chamber. Each channel is provided with its own shutoff valve that can be actuated independently in such a manner that each infeed channel extends from its nozzle inlet in a straight line to the related shutoff valve, and from it in turn over an outfeed channel in a straight line to the common nozzle outlet chamber.
