This is how Alcoa planned to produce aluminum beverage cans in the early 1960s--impact extrusion. The competing process was Reynolds Metals' "draw and iron" or D&I technique, where a cup is formed from a circular blank of flat sheet aluminum and is stretched (ironed) to the final length. D&I can produce cans at a higher rate than impact extrusion, so ultimately it dominated the production of the aluminum cans that drove steel makers out of the beer and soft drink can business. Years after impact extrusion was supplanted by D&I, it was revived by Alcoa to produce aluminum bottles for beer and soft drinks. Our "impacts" were sort of little brothers to the big forgings produced by the guys at Ladish.
Did you work for Alcoa? I was impressed at all the different shapes they could make. I would have liked to have seen how that thing with 3 arms coming off of a circle was made. I also wonder how long the dies lasted on some of the more complicated shapes.

Now I know how all those 1960's aluminum cups and container's were made.
