Abstract: Methods of manufacturing honeycomb-structure-forming extrusion dies having a number of slots for use in producing extruded articles having complex honeycomb patterns and extrusion dies for use in the manufacture of extruded honeycomb bodies. The method includes inserting a die insert having a runner and a number of teeth into a slot of an extrusion die such that each of the teeth blocks at least a portion of the slot of the extrusion die. The method further includes separating the runner from the teeth so that the teeth remain within the slot of the extrusion die.

Abstract: A honeycomb body having a honeycomb structure and a peripheral skin, the honeycomb structure having walls defining a plurality of cells including peripheral cells disposed directly adjacent to the peripheral skin. One or more of the peripheral cells is at least partially defined by a first wall surface, a second wall surface, and a skin surface portion extending between the first wall surface and the second wall surface. A continuously-varying radius extends from a first tangent to the first wall surface along the skin surface portion and to a second tangent to the second wall surface. Other honeycomb bodies, structures, and extrusion dies for forming honeycomb structures are disclosed.

Abstract: Methods for forming an electrode for use in forming a honeycomb extrusion die. The method includes forming, by means of an additive manufacturing process, an electrode includes a base having a web extending from the base. The web defines a matrix of cellular openings. The method further includes forming a secondary electrode having a plurality of pins. The plurality of pins are shaped and arranged so as to mate with the matrix of cellular openings defined by the web of the electrode. The method further includes machining the electrode using the secondary electrode to smooth surfaces of the electrode formed by the additive manufacturing process.

Abstract: An apparatus and method to machine cavities in die blanks having little to no taper. The apparatus includes an elec trode tool (200) including intersecting walls coated with electrically insulating coating (258), an erosion face (204) comprising a cross section of the walls exposed through the electrically insulating coating, and a channel formed by the walls to supply electrolyte to the erosion face, the channels defined by interior surfaces of the walls and having an opening formed by edges of the erosion face. The method includes pulsed electrochemical machining a work piece with the electrode tool.
