The influences of the molding pressure (30, 50MPa) and temperature (100-250°C) on magnetic properties of bonded magnets with Sr-ferrite powders are investigated. The coercivity of the bonded magnets is almost constant 240kAm-1 at the molding temperature of about 200°C or more and independent of molding pressure. The reason why the coercivity of bonded magnets scarcely reduced during molding is due to quasi-isostatic pressure applied for Sr-ferrite powders by resin among the powders, considered by experiments using CIP and powder epoxy resin. The reduction of coercivity of Sr-ferrite powders is caused by mixing the compound. And the reduction of coercivity corresponds with mixing torque, which relates to shapes of Sr-ferrite powders.
