Re: How was this made? (Aluminum Heat Sink - Mystery Manufacturing Method)

It is hard to tell because the pictures are not crisp enough. But looking at the fact that the fins are so close together and they have no draft and they have a shiny and dull side, I would guess it is a bonded fin process.
