Title: METHOD FOR PRODUCING REACTOR, METHOD FOR PRODUCING CORE, CORE, REACTOR, SOFT MAGNETIC COMPOSITE MATERIAL, MAGNETIC CORE USING SOFT MAGNETIC COMPOSITE MATERIAL, AND REACTOR USING SOFT MAGNETIC COMPOSITE MATERIAL
Abstract:
Provided are: a method for producing a reactor, which is capable of improving the productivity and the density, while achieving an advantage in terms of moldability; a method for producing a core; a core; and a reactor. This method for producing a reactor, which is provided with a core that contains a magnetic powder and a resin and a coil that is fitted to the core, comprises: a mixing step wherein 3-5 wt% of a resin is mixed into a magnetic powder; a molding step wherein a mixture obtained in the mixing step and a coil are put into a specific container and are subsequently molded therein; a pressurizing step wherein the mixture is pressurized during the molding step; and a curing step wherein a molded body obtained in the molding step is cured.
