摘要:
In some preferred embodiments, an extrusion die for metallic material capable of obtaining a high quality extruded article can be provide while securing sufficient strength and durability. The extrusion die is provided with a die holding case 20 having a dome portion 21 with an external surface functioning as a metallic material pressure receiving surface 22, the metallic material pressure receiving surface 22 being disposed so as to face rearward, a male die 30 held in the die holding case 21, and a female die 40 held in a front portion of the die holding case 20. The metallic material pressure receiving surface 22 is formed into a convex configuration, and a porthole 24 is formed in the dome portion 21. The central axis A2 of the porthole 24 is inclined to the central axis A1 of the die holding case 20. The metallic material pressed against the metallic material pressure receiving surface 22 is introduced into the die holding case 20 through the porthole 24 and passes through the extrusion hole 11.
