World record castings: we can do it.

320 tons of liquid iron
For one casting

There is only one way to casting dimensions and market requirements: permanent optimisation. However, a casting with record dimensions is always particularly challenging and exciting. While our first record breaker in 1983 weighed in at 168 tons, the dimensions have now grown to a remarkable 320 tons, the current world record.

Our world record castings
Facts & figures

1983First world record casting: 168 t frame for 4,000 t forging press
1987188 t running beam for 15,000 t forming press
1991195 t grinding bowl for cement plant in Indonesia
1998260 t casting of a grinding bowl out of five ladles simultaneously
2009270 tonnes of liquid iron are formed into a head beam for a straightening press
2010Our own world record is beaten after just one year: 283 t head beam casting
2013Our own world records are broken several times:
12 July 2013: 296 tonnes of liquid iron are formed into an presstable for a closed-die forging press with 50,000 t press force
19 July 2013: 301 t presstable casting
11 September 2013: 320 tonnes of liquid iron solidify into a lower beam for a 12,500 t forging press – a world record casting in a new dimension
2015Length record: cross beam casting with a length of 23.5 m weighing 120 t for a two-column milling machine with subsequent machining in the Siempelkamp machining centre

The constant development of manufacturing know-how is just as much a prerequisite for the success of such projects as years of experience and perfect teamwork. This is how we manage even the greatest challenges.
