ABSTRACT:
An apparatus for injection molding a plurality of multilayer, multimaterial plastic containers. A plurality of co-injection nozzles are positioned to feed a plurality of cavities defined by a plurality of injection molds and a source of polymer materials is located upstream of the nozzles. The apparatus also includes a flow channel for each of a plurality of polymer streams to define a path between the polymer source and at least one of the co-injection nozzles such that each of the co-injection nozzles is in communication with one of the flow channels for each polymer stream and the polymer streams enter more than one of the co-injection nozzles. The channels are arranged to provide substantially the same flow experience to each polymer stream.
