Thats 60,000 Tons..per square inch btw

Area is what, 10' x 10'? What's the total force work out to?

Depends on the size of the content of the dies.

Assume 10' X 10' as I said, and empty platens. What is the total
force?

The total force if adjusted to max loading, is 60,000 tons per
square
inch.

Can you provide a cite for your number? Perhaps you could compare it
to other industrial processes you've encountered in your vast
experience.

The subject material here is steel, mostly, and some cast iron.
Typical grades of structural steel collapse to mush when subjected to
a force of around 50 tons per square inch. The very strongest steels
will tolerate about four times as much before squishing into a puddle.

Gunner is talking about the total force delivered by a press, not the
force per square inch. 60,000 tons sounds a little high. I was under
the impression that the world's largest presses will develop a little
more than half that amount of force, but I could be a couple of years
out of date.
