Abstract
PURPOSE: To obtain a comparatively large sized composite magnetic core of excellent electromagnetic characteristics and various shapes by coating the surface of a sintered ferrite magnetic core with a mold ferrite composed of sintered ferrite power and a resin.
CONSTITUTION: The surface of the cylindrical sintered ferrite magnetic core 1, manufactured by usual molding and baking processes, is coated with a mixture of the resin 2a and the sintered ferrite power 2b to obtain the composite mold magnetic core 4, which is manufactured by a compression or injection molding method. In this way, it is possible to obtain magnetic core of a desired shape more easily by injection molding method, as well as with highter dimensional accuracy. The sintered ferrite magnetic core obtained in this way has higher mechanical strength and also much more excellent magnetic characteristics of μ, etc., than those made of only resin and ferrite
