How to Build a 50k Ton Forging Press
2 days ago
- The invention of the jet engine in the 1940s-50s required stronger and lighter aircraft parts, driving the need for large forged or extruded components.
- Large forgings and extrusions reduced part counts, fasteners, weight, and manufacturing costs compared to machining or casting.
- The U.S. Department of Defense's Heavy Press Program (1950s) built four forging presses (up to 50,000 tons) and six extrusion presses, funded at $239 million.
- The presses were leased to private industry and quickly proved cost-effective, saving $500 million by the 1960s and enabling parts for aircraft, spacecraft, submarines, and commercial jets.
- The program's success influenced modern manufacturing, with Tesla adopting large castings (Giga-casting) and China now leading in ultra-large press production.
- Declining U.S. capability in building such machinery risks losing competitive advantage in advanced manufacturing.
