It is disclosed to be a large concentric extrusion die ball (1) with a plurality of annular or conical die mandrel layer (201-205). Each layer is formed between a pair of adjacent annular or conical die mandrel (101-106), said die mandrel (101-106) is a flow path for the molten thermoplastic material to the annular extrusion outlet (110) from the injection port between the defined, and the thermoplastic tubular extrudate extruded through the annular discharge opening 110 is formed in use. Extrusion up through multiple annular layer discharge port (301-305), to form a multilayered product. At least one layer 203 of the ring-shaped or cone-shaped die mandrel having a plurality of melt inlet arranged around the outer periphery of the co-extrusion die, the co-extrusion die to provide a 2
n of auxiliary discharge distribution channels 503 It is connected to the supply channel (403) having a plurality of junctions (403.1,403.2, 403.3), wherein n is the number of branch points. Each auxiliary supply outlet channel is connected to a helical discharge channel 703 corresponding.
