Precision mechanics

Quality and precision are typical Swiss values that are perfectly embodied by the thirty or so mechanical workshops in Valais that manufacture their own products or products for other companies. Thanks to an extensive and high-performance machine fleet, these companies produce parts that are precise to the nearest micron, right through to machines of several tonnes intended for the general public and prestigious customers such as CERN in Geneva.


Founded in 2010, the Stenheim company, based in Vétroz, designs loudspeakers composed entirely of aluminium. Aluminium produces better sound dynamics than wooden speakers, bringing the sound to life. The state-of-the-art components of the damping layers and partitions prevent any resonance for a perfectly clean sound. Stenheim loudspeakers are designed for audiophiles and consumers who demand high-quality sound. Over a hundred pairs are produced annually in Valais.

Stenheim has created some limited- edition loudspeakers for the 50th anniversary of the Montreux Jazz Festival.
