  • Publication number: 20150090418
    Abstract: A method for manufacturing a high-strength golf iron head with a thin striking faceplate includes placing a shell mold onto a rotary table. At least one metal ingot is placed into a crucible portion of the shell mold and melts in a vacuum environment. The rotary table rotates to cause the molten metal to flow into a cavity portion of the shell mold. The rotating shaft is slowly stopped, and the shell mold is removed after pouring. The shell mold is destroyed after the molten metal cools and solidifies, obtaining a casting. A cast product portion is separated from the casting to obtain at least one golf iron head subsequently treated with heat treatment to provide a striking faceplate of the golf iron head with a tensile strength of 280-340 ksi, an elongation of 4%-20%, and a minimum thickness of 1.4-1.8 mm excluding a groove depth of the striking faceplate.

  • Patent number: 8562904
    Abstract: A method for a powder-metallurgical production of metal foamed material and of parts made of metal foamed material includes mixing a pulverulent metallic material including at least one of a metal and a metal alloy; pressing, under mechanical pressure, the mixed pulverulent metallic material so as to form a dimensionally stable semi-finished product; placing the semi-finished product into a chamber that is configured to be sealed pressure-tight; sealing the chamber; heating the semi-finished product to a melting or solidus temperature of the pulverulent metallic material; once the melting or solidus temperature has been reached, reducing the pressure in the chamber from an initial pressure to a final pressure so that the semi-finished product foams so as to form a metal foam; and lowering the temperature of the metal foam so as to solidify the metal foam.

  • Publication number: 20130156637
    Abstract: A method for making an equiaxed investment casting. The method utilizes an ultrasonic generator to send an ultrasonic pulse into molten metal in an investment casting mold. The investment casting mold is positioned within a working zone of furnace having low output induction coils for generating a convection current in molten metal. The ultrasonic pulse separates dendrites growing from the face of the mold inward into the molten metal. Instead, equiaxed grains can nucleate within the molten metal. In addition, the ultrasonic pulse and the low output induction coils circulate the molten metal as solute is rejected from solidifying equiaxed grains. The mixing reduces the effects of segregation in the solidifying alloy and assists in nucleating equiaxed grains.

  • Publication number: 20130093282
    Abstract: A method for forming a rotor assembly including a cast rotor frame includes positioning a preheated rotor core defining a plurality of passages in a mold cavity such that the mold cavity and the rotor core define the rotor frame including a plurality of conductor bars defined by the plurality of passages in fluid communication with first and second end portions of the mold cavity. Molten metal is quiescently introduced into the mold cavity through an ingate and simultaneously flowed through the plurality of passages prior to filling at least one of the first and second end portions of the mold cavity to form the cast rotor frame. Entrained air and impurities may be displaced from the passages by the flow of molten metal and vented or entrapped by a biscuit. The rotor frame and conductor bars thus formed may be characterized by high conductivity, negligible porosity, and minimal oxides.
