| 20080216983 | Method for precision casting of metallic components with thin passage ducts - In precision casting of metallic components with very thin passage ducts, in particular turbine blades, by the lost-wax process, the ceramic core pins provided for forming the passage ducts are covered and stabilised via a low-melting reinforcing coat prior to injection of the wax material required for forming the wax pattern for the production of the ceramic casting mold, with the low-melting reinforcing coat being melted out together with the wax material after the casting mold has been formed on. The ceramic core pins are therefore not damaged during the production of the wax pattern, enabling very thin passage ducts to be formed in the precision casting process. | 09-11-2008 |

The can has first integral liquid-coolant passageways formed therein. The can is configured to have a liquid coolant circulated through the first integral liquid-coolant passageways to thereby cool the can without the can being submersed in a liquid coolant. | 10-23-2014 |
| 20150090418 | Method for Manufacturing a High-Strength Golf Iron Head with a Thin Striking Faceplate - 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. | 04-02-2015 |
| 20150090419 | Method for Manufacturing a High-Strength Blade-Type Golf Iron Head with a Thin Blade - A method for manufacturing a high-strength blade-type golf iron head with a thin blade 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 is heated to melt 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 blade-type golf iron head having the blade with a minimum thickness of 3.5-5.0 mm. The weight of the blade-type golf iron head is reduced by 0.9-2.5%, and the center of gravity of the blade-type golf iron head is lowered by 0.2-0.75 mm. | 04-02-2015 |

Water is present within the wall of the ceramic shell mold. A wax pattern assembly is located within the ceramic shell mold. A heat source is configured for heating at least a portion of the wall of the ceramic shell mold in order to convert at least a portion of the water within the wall of the ceramic shell mold into steam for use in melting at least a portion of the wax pattern. | 12-03-2009 |
| 20120085507 | DEWAX METHOD FOR INVESTMENT CASTING - A method for controlling the dewaxing of a ceramic investment casting shell assembly is provided whereby the shells are immersed in a fluid having a relatively low boiling point, e.g., below about 230° F. The fluid must be hot enough to transfer heat though the shell assembly so as to melt the wax pattern, but low enough so as to limit steam generation as a result of moisture in the shell. By controlling the rate of immersion of the shell in the hot fluid bath, shell cracking can be greatly reduced. | 04-12-2012 |
