Bonded soft ferrite using the injection molding has been expected for many applications because of low cost and complicated shape. However, the effective permeability of it is too low because of the mixture of ferrite powder and resin to have to be increased for its applications.We produced bonded soft ferrites mixed with nylon resin and several kinds of NiCuZn ferrite powders whose inductance was different by the kneading and injection molding. We got the high fludity ferrite compound by trying to make additional quantity of nylon resin and lubricant most suitable. So, we could increase the ferrite powder composition in it, and develop the bonded soft ferrite whose permeability μ' is equal to 30 at frequency 1kHz.
