Extruding
Quality by the metre.
Using all major extrusion processes, both direct and indirect processes, as well as the process for seamless pressed pipes, we are able to press a very broad range of alloys.
OTTO FUCHS has 12 extrusion presses and processes over 140 alloys made of aluminium, magnesium and copper alloys. We offer the full range of extrusion technology on machines with press capacities of 710 to 7,500 tonnes.
Our clients also include our own subsidiary. SCHÜCO International KG offers a wide range of extruded aluminium products for virtually every component to be found in the shells of buildings, as well as being the world leader in solar systems for innovative building shells.
With highly developed extrusion technology, over the decades, OTTO FUCHS has been successful in steadily expanding the load limits in lightweight construction. Apart from a wealth of experience, it is mainly a high level of process expertise that has been developed thanks to constantly expanding range of possibilities.
OTTO FUCHS cold joining method (OFCJM)
The OTTO FUCHS cold joining method is an efficient and economical joining technique. The patented process offers the opportunity to firmly and permanently connect extrusions to each other. Large thick-walled and heavy profiles are a thing of the past. The result of our method is a thin, lightweight profile composite that enables large structural and dynamic loads, offering an unrivalled stiffness-to-weight ratio.
This is how it works:
The condition for the cold joining method is an appropriate design of the individual profiles. On the edges of the profiles there is a tongue and groove system. The assembly process consists of interlocking the profiles to be connected, clamping the parts and pressing the individual profiles. Here, the tongue and groove combinations are squeezed into each other.
The procedure represents an economic alternative to longitudinal seam welding. There is no impact on the material properties due to welding energy and the delay this involves, nor is there any visual impairment of the surface as a result of weld beads or other join-related surface changes.
