PROBLEM TO BE SOLVED: To provide a method for producing a sintered magnet in which a machining margin is reduced at the time of processing of the sintered magnet and the material yield is improved.SOLUTION: A method for producing a sintered magnet includes a magnetic field molding step, a sintering step and a dimension correction step. In the dimension correction step, the sintered magnet is placed in a second mold out of a first mold and the second mold approaching to and being separated from each other, a movable mold composed of the first mold and/or the second mold to move for pressure molding is moved at a first speed, and the speed is reduced to a second speed slower than the first speed to perform dimension correction of the sintered magnet until the movable mold comes into contact with the sintered magnet. |
