Annual report 2009 - Siempelkamp

Siempelkamp’s isothermal forging presses for high performance provide customers
worldwide with a specifi c press speed control which allows incremental adjust-
ments to the lowest velocity as required by the isothermal forging process. The
system is complemented by a tool heating system as well as vacuum and handling
systems.
These presses are predestined to carry out custom-made applications in aerospace
and medical industries with high precision. They do so with the lowest press forces
and best material utilization.
Whether as a stand-alone press or as a combination press which can be integrated
into fully automatic press lines, upsetting, piercing, and drawing presses play an
important role in the range of our forging presses. They are ideal for products with
small wall thickness tolerances produced in large quantities such as bottles or
containers.
Three closed-die forging presses for Alcoa
In 2009 we installed one of three hydraulic closed-die forging
presses of a new forging line with press capacities of 2 x 5,000
and 1 x 8,000 US tons for Alcoa Köfem in Hungary. This forging
line will produce aluminum rims for trucks at the Köfem location
in Szekesfehervar, Hungary. Next to the delivery of the presses, the
scope of supply includes the integration of the existing hydraulics,
the retrofi tting of the control system, the new die changing systems

as well as the start-up. The new presses replace an old press line
consisting of components made by other manufacturers which
has been operating for many years but no longer meets today’s
requirements. After the fi rst press started operation in mid-2009,
the second and third press will be installed in 2010 and 2011
respectively. In order to minimize downtimes during the replacement
process, the presses are individually replaced and put into
operation.
