The invention relates to a manifold 20 for a hot or cold runner 10 and fitted with a manifold plate 201 which comprises a main feed duct 24 for a flowable feed material and further contains a manifold duct system 40 having manifold ducts 41, 42, 43, said system communicating flow-wise through nozzle feed ducts 26 with flow ducts 32 of injection molding nozzles 30 connected to said manifold plate 201. Each manifold duct 42, 42, 43 communicates flow-wise with the main feed duct 24 and/or with at least one manifold feed duct 27, 271, 272, each manifold duct 411 42, 43 issuing into at least one manifold feed duct 27, 271, 272 and/or into at least one nozzle feed duct 26 and each manifold feed duct 27, 271, 272 issuing into a further manifold duct 41, 42, 43 and each nozzle feed duct 20 into the flow duct 32 of each associated injection molding nozzle 30. The manifold ducts 41, 42, 43, the manifold feed ducts 27, 271, 272 and/or the nozzle feed ducts 26 are dimensioned in a way to balance the manifold duct system. The nozzle feed ducts 26 may be arrayed in an n×m matrix, where n=m or n≠m and n≧3. The manifold ducts 41, 42, 43 may be situated in one plane and be horizontal. The manifold feed ducts 27, 271, 272, the nozzle feed ducts 26 and the main feed duct 24 may be vertical. The main feed duct 24 is mounted in a way that none of the nozzle feed ducts is situated directly below the main feed duct 24.
