I first learned about these presses several years ago from the YouTube channel Machine Thinking which is excellent and unfortunately infrequent. The linked video has some excellent footage of these beasts in action. "America's Iron Giants" [VIDEO]

This youtube video seems related. [VIDEO] This is the story of America's massive forging presses built during the cold war used to build America's most advanced machinery - the Heavy Press Program. Modern airplanes, missiles, helicopters, turbines - all have parts made on these giant machines! The Machine Thinking channel seems interesting.

The Machine Thinking channel has a very interesting video on this [VIDEO] I wonder if these modern high pressure casting produce results closer to forging.
