<p>A honeycomb extrusion die constructed from a strengthening base plate (22) comprising a relatively small number of large feedholes (24) and thin die body plate (12) comprising a larger number of relatively small feed holes (18) supplying extrudable material to a discharge slot array (20), wherein the two plates (12,22) are connected by an intermediate compound feed section (32) incorporating branching feed conduits (36) arranged to provide an extrusion path of low flow impedance between the large base plate feed holes (24) and the smaller body plate feed holes (18). The intermediate compound feed section (32) comprises a stacked plurality of thin plates (34), the plates (34) forming an array of branching feed conduits (36). <IMAGE></p> |
