  • Patent number: 8840822
    Abstract: The method of manufacturing a molded article including a component insert-molded in a molding material mixed with solid powder includes an injecting step of injecting the molding material and the solid powder into a molding die, an agitating step of agitating the molding material and the solid powder within the molding die to disperse the solid powder in the molding material, and an embedding step of pressing and embedding the component into an agitated mixture of the molding material and the solid powder.

  • Patent number: 8840821
    Abstract: The exemplary embodiment provides a method of manufacturing a molded article including a component insert-molded in a molding material mixed with solid powder. The method includes an injecting step of injecting the molding material and the solid powder into a molding die, an agitating step of agitating the molding material and the solid powder within the molding die to disperse the solid powder in the molding material, and an embedding step of pressing and embedding the component into the agitated mixture of the molding material and the solid powder while vibrating at least one of the component and the molding die.

  • Patent number: 8593246
    Abstract: A reactor which may be employed in an inverter for automotive vehicles. The reactor includes a coil, a core, a casing, and a positioning member. The core is made of a solidified magnetic powder/resin mixture and has the coil embedded therein. The positioning member is disposed in the casing to position the coil relative to the casing and equipped with fins configured to stir the magnetic powder/resin mixture before solidified. Specifically, the positioning member is designed to perform two functions: one is to fix the location of the coil within the casing, and the other is to stir the magnetic powder/resin mixture through the fins, thus eliminating the need for removing a portion of the magnetic powder/resin mixture adhered to the fins, which leads to improved productivity of the reactor.
