Patent ID: 11040399

Abstract:
The inventive concept relates to a method for manufacturing a metal based component (100, 200) having a cavity (103, 203). The method comprises the steps of: providing a plurality of individual segments (110, 210) corresponding to different portions of the metal based component; arranging the plurality of segments in a stack (120, 220) in such a way that the shape of the stack corresponds to the shape of the metal based component, and that a void (130, 230) is formed in the stack, wherein the shape of at least a portion of the void corresponds to the shape of the cavity; filling at least the first 10 portion of the void with an incompressible filler (140, 240); removing gas from the stack; subjecting the stack to a hot pressing process to form the metal based component comprising the cavity; removing at least a part of the incompressible filler from the metal based component.
