粘结磁体可由磁粉与树脂的混合粉末经压缩成形、注射成形或挤压成形制得。采用压缩成形（冲压成形）时，成形体密度亦即磁粉的体积填充率最高，因此，可得到磁特性比其它方法更高的各向同性粘结磁体。在生产各向异性粘结磁体时，如果在冲压成形时将混合粉末的温度加热到树脂粘 The bonded magnet can be obtained by compression molding, injection molding or extrusion molding of a mixed powder of magnetic powder and resin. In the case of compression molding (press forming), the density of the formed body, that is, the volume of the magnetic powder, is the highest, so that an isotropic bonded magnet having higher magnetic properties than other methods can be obtained. In producing an anisotropic bonded magnet, if the temperature of the mixed powder is heated to resinous viscosity at the time of press forming
