The main Magland site covers roughly 2,700 square meters, and a second milling facility was added in Viuz-en-Sallaz in 2019. The company runs a park of about 40 CNC machines, including 6 machining centers, and employs around 60 people, generating roughly 11 million euros in annual revenue with about 16% going to export markets.
