Abstract (en)

A method for manufacturing a component (1) having an internal damping structure (2) is disclosed. The method comprising the following steps: a) providing core parts (3, 3'), made of a first material with a melting point higher than the manufacturing process temperature, b) arranging the core parts (3,3') in a cast mould in a pattern for receiving a desired internal damping structure (2), c) providing and melting a base material (4), the base material (4) having different physical properties, at least a lower melting point then the first material, then d) casting the component (1) by using the molten base material (4), the base material surrounding the core parts (3,3'), then e) solidification of the base material (4), then f) removing the cast mould, then g) optionally removing a part (3) of the core parts.
