Abstract
A method for manufacturing a component having at least one internal cavity includes the step of providing a core element of metallic material that includes at least one cavity having a first opening covered by a cover element with a first and second side. A form partially surrounds the core element and cover element. The form is filled with metallic filling material and heated in a heating chamber that is pressurized with gas for a predetermined time period at a predetermined temperature and a predetermined isostatic pressure, so that a metallurgical bond is achieved between the core element, cover element and metallic filling material. The core element is arranged such that, after filling the form with metallic filling material, the second side of the cover element is covered with metallic filling material so that the cavity during heating is pressurized to the predetermined isostatic pressure.
