摘要： A honeycomb substrate includes an inner body having an inner skin and an array of inner webs defining an array of inner cells within the inner skin. The honeycomb substrate further includes an outer body having an outer skin formed concentric with the inner skin and an array of outer webs defining an array of triangle cells between the inner skin and the outer skin. The triangle cells are oriented along a radial direction with respect to a center of the inner body. An extrusion assembly for forming the honeycomb substrate includes an inner cell forming die, an outer cell forming die, and a skin forming mask, all mounted coaxially. An outer skin slot formed between the outer cell forming die and the skin forming mask is in communication with feedholes in the inner cell forming die through an opening in the outer cell forming die.

摘要： A process is set forth for electrochemically machining holes in a workpiece, such as a die, in such a manner so as to virtually eliminate surface finish patterns normally introduced by the electrochemical machining process, by randomly forming sequences of patterns of holes extending in rows across the workpiece along its extent, and then rotating the workpiece 180.degree. and randomly forming additional sequences of patterns of holes across the workpiece adjacent those sequences of holes which were formed prior to rotating the workpiece 180.degree..

摘要： Improved batch uniformity delivered to the discharge slots of an extrusion die is obtained by providing a stressor component of reduced cross-sectional area from the feedholes which suddenly increases the linear flow velocity due to its reduced cross-sectional area, and then just as suddenly restores the original flow conditions as it exits the stressor component into a larger diameter channel. A rapid change in particle alignment, due to the cross-sectional flow change, produces a shearing influence on the batch, and functions to produce a more uniform flow as it enters the discharge slot sections of the extrusion die.

摘要： In a metal honeycomb extrusion die which incorporates apertures for the conveyance of extrudable material through the die body toward a discharge opening in the face of the die, the aperture sidewalls are shaped by electrochemical machining or the like to develop a periodically varying aperture size, surface shape or surface finish, superimposed on the conventional randomly varying machined aperture sidewall surface, in order to reduce the adverse effects of random surface variations on extrusion process stability and extruded product quality.
