task. <strong>Siempelkamp</strong> has more than 125 years of experience in designing and building large presses. The engineers’ designs handle the<br />
large forces which occur during crimping, straightening and forging processes. For each new press our engineers benefi t from the<br />
knowledge gained from previous comparable orders. In this way, they develop the optimum solution for the current customer.<br />
This know-how is not only retrieved for new orders, but also for upgrading tasks. After an operation period, in some cases, of more than<br />
50 years, the life expectancy of many central press components (e.g., beams and foundation stands) is almost reached. When it comes<br />
to replacing these parts and upgrading the equipment with state-of-the-art technology, <strong>Siempelkamp</strong> is commissioned. We are just as<br />
committed to modifi cations and upgrades to existing presses as we are to completely new press concepts. Here, we trust in our ability<br />
to unerringly analyze designs from earlier decades, to carry out calculations according to the Finite Element Method (FEM) and to<br />
optimize the design with state-of-the-art technology. The development of Prod-IQ ® Metal Forming is new to <strong>Siempelkamp</strong>: This<br />
software ensures the optimal operation of the press and reduces costs.<br />
the foundation stands made of nodular graphite cast iron in the<br />
company-owned foundry in Krefeld. Ten of these castings weighed<br />
between 200 and 250 t each (220 and 275 US tons).<br />
The following fi nish-machining of the large parts was carried out<br />
by <strong>Siempelkamp</strong> in Krefeld. One of the world’s largest portal milling<br />
machines was used to precisely reach the fi nal dimensions of the<br />
parts. With the 450 MN closed-die forging press Alcoa produces<br />
structural parts made of aluminum for the aircraft industry, such<br />
as fuselage frames with sizes up to 6,000 x 2,000 mm (20 x 6.5 ft).<br />
The goal of the modifi cation is to turn this 450 MN press into the<br />
most state-of-the-art and effi cient forming press in its class.<br />
Because of its large press force and its central meaning for the<br />
American aircraft industry, the giant press has become a “National<br />
Historic Mechanical Engineering Landmark” in the United States<br />

Prod-IQ ® Metal Forming at Fabtech <strong>2009</strong><br />
At Fabtech in Chicago in <strong>2009</strong> <strong>Siempelkamp</strong> presented the new<br />
software package Prod-IQ ® for the process modeling and online<br />
quality control of its metal forming presses. The fi rst real-life<br />
results prove that users save up to 2.5% in material and that<br />
downtimes have been reduced by up to 4%. Key data include:<br />
• suitable for all <strong>Siempelkamp</strong> presses including plate forming,<br />
open-die forging, and closed-die forging presses<br />
• collected data is presented with the help of clear graphics<br />
• quick availability of need-driven information leads to higher<br />
transparency<br />
• characteristic data regarding plant performance, quality,<br />
resource consumption, and costs can be analyzed during<br />
production<br />
• exact traceability of all production steps is guaranteed<br />
• specifi c requests pinpoint the reason for costs<br />
effi ciency increase<br />
• optimized production and processes<br />
• implementing of the most cost-effi cient, condition-dependent<br />
maintenance strategy<br />
