Valais plants’ manufacturing capabilities

„Casting (Steg and Chippis)

The Steg casthouse is dedicated to applications for the aerospace and transportation markets. It produces aluminium slabs for transformation at Constellium’s hot mill at Issoire, France. The casthouse consists of melting and casting furnaces, conventional and electromagnetic casting, homogenizing furnaces, as well as a saw and milling machine.

The Chippis casthouse produces aluminum bars and billets, which are transformed in Constellium’s plants at Sierre (Switzerland) and Singen (Germany).

Plate shop (Sierre)

The plate shop manufactures value-added aluminium plates in a variety of widths dedicated to industry 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.

Extrusion and die shop (Sierre)

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.
