Zusammenfassung:	C-4150 METHOD FOR MANUFACTURING A DIE FOR EXTRUDING HONEYCOMB MATERIAL A method for manufacturing a monolith extrusion die includes the steps of loosely stacking individual tube elements to form a tube stack having reference surfaces therein and feed holes therethrough; fixturing individual shaping teeth together for location with respect to the reference surfaces to form a precise extrusion slot pattern of intersecting rows with the shape of the monolith to be formed by the die. In one method, the shaping teeth are located as a unit and then inserted into a loose tube stack as a unit and then bonded together as a unitary extrusion die. In another method, the shaping teeth are fixtured in a loose tube stack as it is formed and thereafter the fixtured teeth and tube stack are bonded to form a unitary extrusion die.
