The Steg casthouse is dedicated to applications for the aerospace, industry, automotive and defense markets. It produces aluminum slabs for rolling at Constellium’s hot mill at Issoire and Neuf-Brisach, France. The casthouse consists of melting and casting furnaces, conventional and electromagnetic (EMC) casting, homogenizing furnaces, as well as a saw and milling machines.
The Chippis casthouse produces aluminum bars and billets, which are transformed in Constellium’s plants at Sierre (Switzerland) and Singen (Germany).
The plate shop manufactures high value-added aluminum plates in a variety of widths dedicated to industry, defense and aerospace. The plates undergo several thermal and mechanical treatments to modify their properties according to customer needs. The plate shop consists of quenching furnaces, stretchers, straightening machines, ageing furnaces, saws and surface milling machines.
The extrusion and die shop produces large profiles used in the transportation, automotive, industry and construction sectors (including molding, machinery, tooling and general engineering). The extrusion shop is equipped with 2 large extrusion presses and furnaces for tempering, quenching and annealing, enabling us to provide highly sophisticated large sections e.g. for the rail industry. The extrusion and die shop is also equipped to perform in-house US control. Finally, added value operations (machining, welding, bending, kitting, assembly) are provided either by in-house CNC machining or in cooperation with an established and proven sub-supplier network.
Constellium’s plants in Valais are well recognized for the high quality of products delivered to customers. To offer the best-in-class quality, Constellium has several laboratories in Valais:
- The Test Material Laboratory, where technicians work on destructive tests to characterize the mechanical properties of the products.
- The Metallurgy Expertise Laboratory, where metallurgical and microscopic tests are conducted to control the macro and microstructures of the plates produced.
- The Spectrometry Laboratory, to control the chemical composition of the alloys produced at the casthouse.
Constellium in Valais has his own Apprentice Center, recognized by the Canton and offers various possibilities in technical apprenticeships. They actually train about 50 people.
