Die tooling (4) is formed by forming a series of passages (50,52,60,62) extending in the length of the tooling where each passage has a circumference defined within a body member (70) of the tooling (4). Preferably the passages are primarily formed using a drilling procedure. The passages define a predetermined pattern of outlets (54,56) adjacent the extrusion outlet or outlets (22,32). The passages between the inlets and outlets can be formed in a series of connected body members with each passage extending through each body member (70). Die tooling of this design is more robust and cost effective to manufacture. |
