Our own foundry and machining center for large parts<br />
Our foundry manufactures large castings with weights of up to<br />
300 t (331 US tons). These parts are then fi nish-machined on one<br />
of the world’s largest portal milling machines. This picture shows<br />
one of two lower beams with a weight of 235 t intended for the<br />
modifi cation project of the closed-die forging press at Alcoa,<br />
Cleveland.<br />
240 t (265 US tons) part during machining<br />
Each year the foundry produces approx. 60,000 t (66,139 US tons) of molten iron;<br />
castings with weights of more than 200 t (220 US tons) are the daily routine.<br />
The world record from May <strong>2009</strong> proves the capacity of the <strong>Siempelkamp</strong> foundry.<br />
We have produced the heaviest casting ever made of nodular graphite cast iron.<br />
All from one source<br />
Whether it is the versatility of our product range or our process technology which<br />
convince our customers, both are the result of a repetitive process in which<br />
engineers of different fi elds take part. A continuous dialogue between design<br />
engineering, engineering, foundry and production departments as well as close<br />
cooperation with the customer ensure that the optimal solution is found for each<br />
Custom-made upgrading for Alcoa Forging & Extrusions<br />
Products<br />
In July <strong>2009</strong> Alcoa Forging & Extrusions ordered from us the<br />
engineering and production for castings used in upgrading one<br />
of the world’s largest closed-die forging presses.<br />
For the Alcoa plant in Cleveland, Ohio, <strong>Siempelkamp</strong> cast 14<br />
large castings for the upper, lower and moving beams, as well as<br />
450 MN closed-die<br />
