A method for manufacturing a component (100) having at least one internal cavity (11) characterized in comprising,
- providing at least a first preformed core element (10) of metallic material that comprises at least one cavity (11) having at least a first opening (12), which is covered by a cover element (30) having a first side (33) and second side 34, wherein said first side (33) is gastight joined to said at least first core element (10);
-providing a form (50), at least partially defining the shape of the component (100), that at least partially surrounds said at least first core element (10) and said cover element (30);
-filling said form (50) with metallic filling material (60)
- heating during a predetermined time period at a predetermined temperature and a predetermined isostatic pressure so that a metallurgical bond is achieved between said at least first core element (10), said cover element (30) and said metallic filling material (60), wherein
said at least first core element (10) is arranged such that, after filling said form (50) with metallic filling material, said at least second side (34) of said cover element (30) is covered with metallic filling material (60) and such that said cavity (11) during heating is pressurized to the predetermined isostatic pressure. |
