Zusammenfassung:	A method of manufacturing a component of a turbomachine by powder metal hot isostatic pressing is disclosed, which uses a container defining outside surfaces of the component. A metal insert is located inside the container before filling the container with metal powder, and the insert is left in the component after the end of its manufacturing. In an embodiment, a metal core is located inside the container before filling the container with metal powder, and the core is removed from the component before the end of its manufacturing. In this way, net shape surfaces may be obtained without manufacturing trials.
