摘要： A rare earth bonded magnet comprising a rare earth magnet powder bonded with a binder resin is manufactured by extrusion or injection molding. A rare earth bonded magnet manufactured by extrusion molding has a rare earth magnet powder content of 78.1 to 83.0 percent by volume. A rare earth bonded magnet manufactured by injection molding has a rare earth magnet powder content of 68.0 to 76.0 percent by volume. Preferably, the rare earth metal powder is at least one of Sm--Co alloys, R--Fe--B alloys wherein R is at least one of rare earth elements including Y, and Sm--Fe--N alloys. Preferably, the thermoplastic resin include polyamide, liquid crystal polymer, and Polyphenylene sulfide. Preferably, the rare earth bonded metal has a void ratio of 2 percent by volume or less. A rare earth bonded magnet is manufactured by kneading a rare earth magnetic composition comprising a rare earth magnet powder and a thermoplastic resin, and by extruding or injecting the mixture after kneading. A rare earth magnetic composition used for extrusion molding contains a rare earth metal powder of 77.6 to 82.5 percent by volume, and a rare earth magnetic composition used for injection molding contains a rare earth metal powder of 67.6 to 75.5 percent by volume. Preferably, such rare earth magnetic compositions further comprise an antioxidant, such as a chelating agent. Thus, a rare earth bonded magnet showing excellent moldability and magnetic properties and high mechanical strength at a minimum binding resin can be obtained.

摘要： A die for extrusion molding a resin bonding magnet. In the production of the magnet, a molten mixture of a magnetic powder and a resin are introduced into a cavity between an outer die and a mandril to which a magnetic field is applied. A steep temperature gradient along the die axis direction of the molten mixture and the cavity is achieved by making the outer die of a multiple layer structure along the die axis direction, utilizing two or more axially adjacent blocks or sheets made of the same or different materials whereby fluidity of the molten mixture is sufficiently high at the inlet of the cavity to enable the magnetic powder in the molten mixture to be sufficiently orientated in the direction of the magnetic field and then the molten mixture is cooled to a solidified state so that the orientation of the magnetic powder is not disturbed, thereby producing a magnetic having high magnetic properties.

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, 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 is then cooled and solidified when passing through a tip portion 43, thus obtaining a molded body 12 of a rare-earth-bonded-magnet.

摘要： The addition of a chelating agent or a chelating agent and an antioxidant in combination to a rare-earth bonded magnet composition and a rare-earth bonded magnet comprising a rare-earth magnetic powder and a resin component can provide improved moldability and magnets having high performance and high corrosion resistance. Further, the regulation of property values of the magnet composition enables the occurrence of troubles to be avoided during molding, resulting in improved productivity. Furthermore, the use of at least two resins as a resin component in an extruding composition contributes to improvement in moldability and consequently increase in throughput. Furthermore, the use of extrusion, involving setting by cooling, and not compression molding in the production of magnets can provide high-density, high-performance magnets.

摘要： A rare earth bonded magnet formed by bonding a rare earth magnet powder with a binding resin contains the rare earth magnet powder, and a thermoplastic resin serving as the binding resin in an amount within a range of from 1 to 5 wt. %, and preferably further contains an oxidation inhibitor. As the rare earth magnet powder, for example, at least one of an Sm--Co alloy, an R--Fe--B alloy (where, R represents at least a kind of rare earth elements including Y) and an Sm--Fe--N alloy can be appropriately used.

In such a rare earth bonded magnet, the thermoplastic resin covers the outer surface of the rare earth magnet powder 2, and is present so as to prevent particles of the magnet powder from coming into contact with each other. Such a rare earth bonded magnet should preferably have a void ratio of no more than 2 vol. %.
