I've been looking at aluminium extrusion videos on youtube for the past half-hour trying to work out how the dies have a circular void in the middle.
Turns out it's a second die (called a mandrel) that locks into the main die (called a cap), and the hot pressurised aluminium flows around the mandrel then forms back into one piece as it goes through the cap.
- MengerSponge 4y agoIt's the same as pasta, but with different temperatures and tolerances!
- iancmceachern 4y agoThe coolest part (pun intended) is how they cool the semi-melted aluminum after extrusion, in long tanks of water, that have no sides, the sides are made from water pressure made from directing water flow.
