There were 30,000 tons, 40,000 tons and 80,000 tons of die forging presses built in 2012 alone. Until the last two years, several huge presses were developed explosively. The Soviet Union built two huge 75, 000-ton die-forging presses around 1961.įrance bought a 65,000 ton die-forging press from the Soviet Union in 1976 and developed a 40,000 ton die-forging press in 2005 in cooperation with Germany.Ĭhina’s first 30, 000-ton die-forging press stalled for nearly 40 years after it was built in 1973. In 2001, another 40,000-ton die-forging press was built at the Shultz steel mill in California. The United States built two of the world’s largest 45,000 ton die-forging presses around 1955, which are still in use today. There are only a few countries in the world that can make such a hydraulic forging press.Ĭurrently, only China, the United States, Russia and France have more than 40,000 tons of die forging presses in the world. The giant die-forging hydraulic press is a national treasure class strategic equipment which symbolizes the strength of the heavy industry. The 80,000-ton die-forging hydraulic press is 27 meters high on the ground and 15 meters underground, with a total height of 42 meters and a total weight of 22,000 tons, which make it the most powerful and strongest hydraulic press in the world It is often used in pressing and pressing forming processes, such as forging press, stamping, cold extrusion, straightening, bending, flanging, sheet drawing, powder metallurgy, pressing, etc. Hydraulic press machine (also known as hydraulic oil press) is a machine that makes use of the static pressure of the liquid to process metal, plastic, rubber, wood, powder products.
The hydraulic press is a kind of machine which uses the liquid as a working medium to transfer energy based on PASCAL’s principle to realize various technique. See also: What is Hydraulic Press Machine?
