World Records

World record castings at Siempelkamp a long tradition

Innovative developments and continuous new challenges from our customers allow us to achieve incredibly high performance, e.g. in the form of world record castings. Although we already have experience with world records, the tension amongst the employees involved in the casting is very high every time. The proficient and competent work of all participants in the manufacturing process means, however, that we are always confident of working successfully with these dimensions.

Record project: Alcoa‘s closed-die forging press: A landmark will once again be updated!

This fall the last component parts for a Siempelkamp reference project set sail to Alcoa Forging & Extrusions. In 2009 Alcoa ordered a total of 14 castings and several custom components for the refurbishment of one of the world‘s largest closed-die forging presses located in Cleveland, Ohio. The corresponding engineering was commissioned back in 2008. After the retrofi tting, the 50,000-ton press (450 MN) will be the most up-to-date and effi cient forging press in its class! For Siempelkamp Giesserei this order represents a world record, for the entire Group it is shared work on a ‘Super Giant’.
