Annual report 2009 - Siempelkamp

Clutch-controlled screw presses are representatives of mechanical closed-die forging presses. The current NPS series operates with
press forces of 4/5 MN to 25/40 MN. These presses produce bicycle blanks, rings, fl anges, axle stubs, housings, hand tools made of
steel, aluminum, titanium as well as parts for medical technology.
The clutch-controlled screw press has the highest energy potential of all mechanically driven forging presses. Therefore, this press type
is especially well suited for forging extruded parts, axle stubs, and similar parts for which a high energy capacity is necessary.
Siempelkamp has positioned itself as one of the world’s few highly experienced manufacturers of compacting presses. These presses
have a press force of 90 MN and are used for the compacting of titanium sponge or chips. Compacted titanium sponge is the starting
product for precision forgings used in the aerospace industry. The strict test criteria in the aerospace industry demand high product
quality. Knowing how important quality is in the manufacturing process of titanium, corresponding orders for Siempelkamp com-
pacting presses are our best reference!
Compacting press for Ust-Kamenogorsk
A Siempelkamp 2 x 90 MN compacting press for titanium sponge
was installed at the Ust-Kamenogorsk Titanium & Magnesium
Plant (UKTMP) in Kazakhstan in 2009.
The distinct feature of the new press is its double-sided action.
Because it has a press capacity of 2 x 90 MN, it generates an
extremely high specifi c forming pressure which so far is new for
the compacting of titanium sponge in presses of this dimension.
The resulting compacts have a high density and, consequently,
are easier to process and lead to end products with a higher
quality.
The scope of supply contains the design, manufacture, delivery,
the hydraulic system, a die change system with different press
dies as well as the complete control system with visualization.
Furthermore, the Siempelkamp team will perform several onsite
services including the monitoring of the installation, the start-up
and the calibrating of the entire press. The start-up of the press is
scheduled for April 2010.
