摘要： The present invention provides a method for manufacturing a rare-earth bonded magnet as follows: A compound 10 prepared by pelletizing a kneaded mixture of a rare-earth-bonded-magnet composition containing a rare-earth magnet powder, a binder resin and an antioxidant is stored in a hopper 91, and fed into a cylinder 3 through a feeding pipe 92; meanwhile, piston 81 is extended by driving an oil-hydraulic cylinder 8, and moved downward to compact the compound 10 fed into the cylinder 3 while gradually transferring the compound downward inside the cylinder 3; the cylinder 3 and a heating portion 41 are heated by heaters 5, and the compound 10 passing therethrough is heated to become a melted material 11; and the melted material 11 is continuously extruded out from a die 4 in the downward-vertical direction, and then cooled and solidified when passing through a tip portion 43, thus obtaining a molded body 12 of a rare-earth bonded magnet. According to this manner, a rare-earth bonded magnet exhibiting superior moldability, excellent magnetic properties and high dimensional precision can be obtained with a smaller amount of binder resin while taking advantage of the benefits of extrusion-molding.

摘要： A composition for a rare earth bonded magnet, the rare earth bonded magnet and the method for manufacturing the rare earth bonded magnet are provided that produce little decline in mechanical strength caused by the addition of a lubricant and have excellent molding properties. The rare earth bonded magnet of the present invention is manufactured from the composition for the magnet that contains rare earth magnetic powder, binding resin containing thermoplastic resin, and fluorine-based resin powder, by compaction molding, extrusion molding or injection molding. The fluorine-based resin powder has the properties of improving mainly lubrication between a molding and a metallic mold. The content of the fluorine-based resin powder in the composition for the rare earth bonded magnet is preferably less than 20 vol% relative to the thermoplastic resin, and the particle diameter of the fluorine-based resin powder is preferably 2-30µm.

摘要： A process for producing a rare earth bond magnet comprising the steps of first mixing rare earth magnetic powder, a binding resin and an anti-oxidant at a predetermined ratio, kneading the mixture at a temperature higher than a thermal deformation temperature of the binding resin, granulating or classifying the kneadate to a mean particle diameter of, e.g., about 0.01 to 2 mm, press-molding the resulting granular material at a first temperature at which the binding resin is softened or molten, and cooling the resulting molded article under a pressure to a second temperature lower than at least the first temperature. Consequently, a rare earth bond magnet having a low porosity, high dimensional accuracy and excellent magnetic characteristics can be obtained.
