World's Biggest Forging Press
Aluminum Company of
America (ALCOA), Forging Division in Cleveland in 1954 began operating the
world’s largest fabrication tool. It was a 50,000-ton hydraulic forging press
critical in development of aircraft and aerospace vehicles. It was designed and
built for the U.S. Air Force by the Mesta Machine Company of Pittsburgh,
following the discovery a 30,000-ton press used by the Germans in World War II
(later acquired by the Soviet Union). It remains in use as one of the world’s
largest hydraulic presses.
What is a Press Forging?
Press Forging is a process whereby slow pressure
is continuously applied to the area to be shaped. The pressure extends through
the material which can be either hot or cold. Cold press forging is primarily
used on thin materials, while hot press forging is preferred for
larger work such as parts for trains and heavy machinery.
What is a Hydraulic Forging
A basic forging press exerts a force that presses
steel, aluminum, or other metal alloys into a shape, determined by the shape of a "forging
die." Forging presses are used for manufacturing everything from gears to
automotive wheels. Hydraulic presses are primarily used for large or complex
dies and for extrusion. They work via high-pressure fluid produced by hydraulic
pumps and are used in forging large airplane components, for example.
