<p>A method for manufacturing a monolith extrusion die (10) includes the steps of loosely stacking individual tube elements (12) to form a tube stack (50) having reference surfaces (12a) therein and feed holes (30) therethrough; fixing individual shaping teeth (18) together for location with respect to the reference surfaces (12a) to form a precise extrusion-slot pattern of intersecting rows (32,34) with the shape of the monolith to be formed by the die (10). In one method, the shaping teeth (18) are located as a unit and then inserted into a loose tube stack (50) as a unit and then bonded together as a unitary extrusion die (10). In another method, the shaping teeth (18) are fixed in a loose tube stack (50) as it is formed and thereafter the fixed teeth (18) and tube stack (50) are bonded together to form a unitary extrusion die (10).</p> |
