Re: How was this made? (Aluminum Heat Sink - Mystery Manufacturing Method)
A google search of
images of skived fin heat sink
produces parts that clearly meet what I'd expect from skiving, and do not look like the original part, at least not to me.
The rough side, and what looks like flakes of oxidized scale on the "Single fin - dull side", leave me in the cast camp. I still don't know how they cast it unless they cast the individual fins and bonded them to the base plate. It kind of looks like that in the movie, but of course that is what I'm looking for, and at times, there is enough blurryness to see the Mona Lisa. I'll ask some of the experts at work for other opinions.
