Re: How was this made? (Aluminum Heat Sink - Mystery Manufacturing Method)
Looking at the pictures again, I go with the knife (shaving) option. Shiny side is the "cut" side. Dull side is the "ripped" side. The fins are set even, vertical, straight, as a separate operation. This is a low waste and fast process. It has to be a big fun machine to watch. AAvid, and other engineered extrusion heatsink companies do not use this process.
