  • Patent number: 6932875
    Abstract: A golf club head has a metal base, face and tubular neck and a carbon-fiber cover. The face extends up vertically from one edge of the base. The tubular neck is integrally connected to the base and the face. The cover is made of a carbon-fiber material and is securely attached to the base and the face. Because the carbon-fiber material is lighter than metal, the area of the face is enlarged. In addition, the shock absorbing effect of the golf head club is also improved.

  • Publication number: 20040108089
    Abstract: A method for producing a golf club head consists of preparing at least two wax models for the golf club head; combining the at least two wax models; coating the combined wax models with a layer of sand mortar to form a sand mortar mold; removing the wax from the sand mortar mold; pouring molten liquid into the sand mortar mold; breaking the sand mortar mold to leave a metal golf club head. The metal golf club head is further cut off any surplus metal and polished to complete a one-piece metal golf club head.

  • Publication number: 20030139226
    Abstract: A golf club head has a body and a carbon filter block. The body has a face defined on one side of the body. A tubular neck is integrally formed on one end of the body. A cavity is defined in the body opposite to the face. The carbon fiber block is mounted in the cavity. Because the carbon fiber material is lighter than metal, the area of the face is enlarged. In addition, a better shock absorbing effect is achieved due to the arrangement of the carbon fiber block.

  • Publication number: 20020004427
    Abstract: A golf club head includes a head body with a tapered weighting member formed inside the head. The tapered weighting member has a top portion and a bottom portion having a thickness larger than that of the top portion to provide a low center of gravity in order to maintain stability of the head during a swing. The weighting member is made of metal which has rigidity lower than that of the material made of the head, and the weighting member is evenly formed behind a striking face of the head. By such an arrangement, the head is able to provide a shock absorbability thoughout the entire striking faces.
