20110132562 | WAXLESS PRECISION CASTING PROCESS - Alloy products are produced with a waxless casting process. A model of a ceramic casting vessel ( | 06-09-2011 |
20110204205 | CASTING CORE FOR TURBINE ENGINE COMPONENTS AND METHOD OF MAKING THE SAME - A turbine engine component, such as a turbine blade or vane, with complex internal features can be cast using a core having a first region with normal resolution features and a second region with high resolution features. The core can be formed from a single structure. Alternatively, the first region can be defined by a first ceramic core piece, which can be formed by any conventional process, such as by injection molding or transfer molding. The second region can be defined by a second ceramic core piece formed separately by a method effective to produce high resolution features, such as tomo lithographic molding. The first core piece and the second core piece can be joined by interlocking engagement, such as by male and female dovetails. The high resolution features can be effective to produce high efficiency internal cooling features in the cast component. | 08-25-2011 |
