Heavy-Duty Extrusion Presses for Large Profile Applications

Axel Bauer, SMS Meer GmbH, Extrusion Division, Monchengladbach, Germany


ABSTRACT—SMS Meer, a member of the SMS group, is currently building several heavy
extrusion presses for large profile applications. Two of these presses have a nominal pressing
force of 150MN and are considered to be the largest state-of-the-art front-loading presses in the
world! All of the fast-developing countries like China, Russia, India, or Brazil these days do have
infrastructure programs that include new railway lines. These projects comprise high-speed lines
for the long-distance connections, as well as investments in inter-city connections, commuter
trains, or metros. Eventually all of this leads to an increasing market for large profiles, and since
the numbers of operative heavy presses were limited, big investments in extrusion plants for
heavy-duty and large sections are now being made, especially in China. But it is not only the
number of presses; it is also the size of the presses that is constantly increasing over the last years.
While a 65MN press was considered to be a huge press a few years ago, today some people
would call it only “medium-size.”
