See How The Amazing New Mac Pro Is Stamped From A Single Aluminum Puck [Video]

Remember the Unibody MacBook, so called because it was milled from a single chunk of aluminum? Now that most of Apple’s products are made that way, you never hear the term “Unibody” any more – it’s like cars: you only write “16-valve”, “ABS” or “fuel injection”on the back when you’re showing off something new.

It’s time, then, for a new construction method, and the new “trashcan” Mac Pro has one. It’s called Impact Extrusion, and it is super cool.

Impact extrusion works by dropping a solid slug of aluminum into a hole, and ramming a piston in after it. The slug then pops out of the gap between piston and hole like a straight-sided metal balloon. It’s pretty spectacular[1]:

Incredible, right? I don’t know what kind of force is needed to make the edges of the puck pop up like that, but I’m pretty sure I wouldn’t want to get my fingers anywhere near it. It also looks a lot quicker than I imagine unibodying[2] to be.

I wonder how long it’ll be before someone uses this method to make an actual trashcan?

    That’s pretty quick. I’ll bet it’s many times faster than how Apple made its cases for the old Mac Pro.
