The invention relates to a core for high- pressure die-casting, which core is intended to form a cavity (21) in a high-pressure die-cast piece (22). The core (20) includes a heart (23) made from a disintegrable material, the external surface of which is formed of a reinforcement layer (24). The reinforcement layer (24) is an essentially unified metal layer (25) cast around the heart (23) in a pattern. In addition, the metal of the metal layer (25) is the same metal as that of the high-pressure die-cast piece (22), and is arranged to attach to the high-pressure die-cast piece (22). The invention also relates to a method in high- pressure die-casting and a high-pressure die-cast piece. |
