Abstract: Methods for extruding a ceramic-forming mixture through a honeycomb extrusion die (10), methods for forming a green honeycomb extrudate from a ceramic-forming mixture, methods of preparation of a honeycomb extrusion die (10) that extrudes a ceramic-forming mixture, and systems including a honeycomb extrusion die (10), ceramic-forming mixture, and abrasive flow media. The method of extruding a ceramic-forming mixture through a honeycomb extrusion die (10) includes conditioning the honeycomb extrusion die (10) by extruding an abrasive flow media through the slots (20) of the die (10) prior to extruding the ceramic-forming mixture through the slots (20) of the die (10). The abrasive flow media includes abrasive inorganic particles dispersed in a flowable carrier. The ceramic-forming mixture includes one or more types of inorganic ceramic-forming particles. The abrasive inorganic particles in the flowable carrier have a particle size distribution that corresponds to that of at least one type of the ceramic-forming particles in the ceramic-forming mixture.

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.
