摘要： The present invention comprises a method of making a golf club head by casting a molten titanium alloy and thereafter removing the alpha case that is formed on the surface of the titanium by means of a conformal milling process. The conformal milling process uniformly dissolves the alpha case without distorting the underlying metal. The reduction in wall thickness caused by the conformal milling results in a concomitant reduction in the weight of the part without any loss in the critical impact strength of the part. In fact, impact strength is increased. This weight can then be redistributed as a supplemental weight member, which can be used to lower the center of mass of the club. The weight member can further be positioned on the sole plate or club body in such a way so as to permit fine tuning of the location of the center of mass of the club, as well as shaped so as to increase the polar moment of inertia of the club head about the golf club shaft.

摘要： A casting device for metallic product includes a main unit 1 having a pressurizing chamber 14 and casting cavities 16 for accommodating a metallic material M, a pressurizing unit 3 for pressurizing the metallic material M contained in the pressurizing chamber 14 to cause the metallic material to flow into the casting cavities 16 and a blade unit 4 provided between the pressurizing chamber 14 and the casting cavities 16. The blade unit 4 includes a scraper edge 41 for scraping the outer layer of the metallic material M pressurized by the pressurizing unit 3. After the end of the scraping operation for the outer layer M2 of the metallic material M, the blade unit 4 is moved by the first driving unit 51 from the scraping position A1 to a disengaging position. Thereby, the metallic material can be readily separated from the blade unit.

摘要： A hand-held casting device for molding a hollow pointed, grooved, and twice throughbored bullet including a pair of handles, a pair of jaws, a mold, a pin, and a bracket. The mold includes first and second halves and two rods passing at different elevations and orthagonally into the mold for providing the two throughbores in the bullet The length of the bracket is such that upon opening the mold, the pin moves in contact with the mold first half until such time as the bracket contacts the mold second half forcing the pin to leave the mold first half and move towards the mold second half until such time as the bracket contacts the mold first half causing the mold to no longer be able to separate and positioning the pin equidistantly between the mold first and second halves.

摘要： An apparatus A for cutting off an unnecessary object deposited on a casting includes a motor having a rotary shaft 3 adapted to be rotated at a high speed, and a disk-shaped diamond tip saw 2 mounted at a tip end 4 of the rotary shaft 3 and adapted to be rotated by the rotation of the rotary shaft 3 to cut off the unnecessary object 9 on the casting 8, so that the tip saw 2 is rotated at a rotational speed in a range of 6,000 rpm to 8,000 rpm. Thus, the rigidity of the diamond tip saw 2 rotated at the high speed is increased by a centrifugal force provided by the diamond tip saw 2 itself and a gyroscopic moment effect to reduce the thickness of the diamond tip saw 2 can be reduced by a value corresponding to an increment in rigidity of the tip saw 2, whereby the amount of diamond tips (diamond blades) used can be decreased; an energy-saving for a cutting power can be achieved, and the amount of chips produced upon the cutting of the unnecessary object can be reduced.
