摘要： PROBLEM TO BE SOLVED: To obtain an extruded stock small in generation of the twist during the extrusion by allowing a stock inlet side relief part of an extruding die to have elliptical shape or polygonal shape having smooth angle. SOLUTION: A stock inlet side relief part 11R of an extruding die 11 is of elliptical conical shape with the major diameter d1 and the minor diameter d2. A die choke part 11C is provided opposite to the stock inlet side relief part 11R, and the die choke part 11C is preferably of truly circular conical shape with the diameter d3. An intermediate die bearing part 11B is of truly circular straight shape of the diameter d3. The die is for hot extrusion, and preferably the die for extruded stocks having an eccentric long hole or a compound part of different materials. Extrusion is selected from the direct extrusion (forward extrusion), the indirect extrusion (backward extrusion), and the hydrostatic extrusion (lubricating extrusion).
