Beschreibung
Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a manufacturing method of parts for a combustion engine or a turbine, in particular, a manufacturing method of hollow-valve parts such as a valve cone or a valve element, the method being able to process even other materials advantageously. SOLUTION: In the present invention related to the manufacturing method of the parts for the turbine, metal powder and/or metal alloy powder are mixed in a compounder with a binding agent and a flux if necessary, the mixture is shaped by injection moulding, the shaped compound is chemically separated and the chemically separated compound is thermally separated at a temperature no more than 450°C, and the chemically and thermally separated compound is sintered at a temperature no more than the melting temperature of the metal and/or metal alloy for manufacturing the part. The part can be combined with each other by conventional clamping and force-clamping methods and also a molten bonding method. COPYRIGHT: (C)2008,JPO&INPIT
