Abstract
PURPOSE:To prevent possible cracks with a promoted magnetic anisotropy and an even molding density by means of a parallel section over 1,000 times as long as the grain size of the ferrite powder arranged at the tip of a extrusion outlet of the die connected to the outlet of a molding machine. CONSTITUTION:The parallel section 3 over 1,000 times as long as the grain size of the ferrite powder is provided at the tip of the extrusion outlet of the die connected to the outlet of the molding machine. Positioned following a tapered section, this proper parallel section 3 eliminates roughness on the surface of the molding thereby uniformizing the molding density. Thus, the magnetic anisotropy accompanied by the extrusion effect or the like can be promoted and variance in the molding density checked thereby preventing possible cracks in the sintered body.
