FABRICATION METHOD OF METAL MOLD FOR EXTRUSION FORMING, AND HONEYCOMB STRUCTURE FABRICATION METHOD
The die for extrusion molding of the present invention includes: a first face; a second face formed opposite the first face; a raw material supply section with a first through hole that extends from the first face toward the second face; and a molding section with a second through hole that extends from the second face toward the first face so as to communicate with the first through hole, wherein the die includes a treated surface on the inner wall surface of the second through hole, the treated surface being obtainable through the steps of: machining a material of the die to form the material into a die having a predetermined shape and to form a machining-affected layer on the inner wall surface of the second through hole in the molding section; forming an oxidized layer by heating the machining-affected layer to oxidize the layer so as to convert the machining-affected layer into an oxidized layer; and removing the oxidized layer.
