摘要： A manufacturing process for blades (5) of a turbomachine, e.g. a gas turbine engine for an aircraft. In the process: a) a ceramic core piece (1) that comprises at least two ceramic core elements (1', 1", 1‴, 1ʺʺ) and a clamping part (2) that connects the ceramic core elements, is positioned in a wax forming device (100), subsequently; b) a molten wax material (W) is applied to the outside of the ceramic core piece (1) in the wax forming device (100) and the wax is allowed to solidify, and subsequently; c) at least two turbomachine blades (5) are cast using a crystallographically-oriented metal casting process and the wax (W) and the ceramic core piece (1) are removed.

摘要： There is provided a method for manufacturing a turbocharger bearing housing which can prevent a collapsible core from being damaged when molten metal is cast in the mold. The method for manufacturing a bearing housing 20 of a turbocharger 10 is that the bearing housing 20 of the turbocharger 10 is formed with a cooling passage 33 for circulating cooling liquid by casting using a collapsible core 50. The collapsible core 50 includes the end part forming portions (a one end forming portion 52 and an other end forming portion 53) corresponding to the end portions of the cooling passage 33 and having a substantially elliptical cross-section, and a fixing portion 54 holding the end part forming portions and being embedded in a mold 60 and fixed to the mold 60.

摘要： A method is provided for making a mold for casting advanced turbine airfoils (e.g. gas turbine blade and vane castings) which can include complex internal and external air cooling features to improve efficiency of airfoil cooling during operation in the gas turbine hot gas stream. The method steps involve incorporating at least one fugitive insert in a ceramic material in a manner to form a core and at least a portion of an integral, cooperating mold wall wherein the core defines an internal cooling feature to be imparted to the cast airfoil and the at least portion of the mold wall has an inner surface that defines an external cooling feature to be imparted to the cast airfoil, selectively removing the fugitive insert, and incorporating the core and the at least portion of the integral, cooperating mold wall in a mold for receiving molten metal or alloy cast in the mold.

摘要： System and method for fusing a chaplet to a casting. The method includes placing the chaplet on an upper surface of a mold; distributing a heater around the chaplet such that the heater is not exposed to the casting; placing a core on the chaplet such that the mold and the core define a component of a machine; heating the chaplet with the heater to a predetermined temperature; and pouring the casting in the mold, around the core and the chaplet, when the chaplet is at the predetermined temperature.
