About Decobar Swiss
Decobar Swiss SA is a precision machining service provider specialized in Décolletage, based in Yverdon-les-Bains in Switzerland. The company manufactures complex, high-precision turned parts for the watch industry, general mechanical engineering, medical technology and micromechanics. Machining ranges from micro-Décolletage of miniature parts up to Ø 4 mm, via series production of precision components up to Ø 20 mm, to turning of technical parts up to Ø 51 mm. The modern machine park comprises CNC turning machines from Tsugami, Star, Citizen and Miyano as well as a twin-spindle turning center from Nakamura-Tome. As a member of the TEC Group, Decobar can draw on a partner network for heat treatment, decoration, finishing and assembly, and can thus offer complete manufacturing solutions from a single source. A second site in Vallorbe (ZI le Day) is planned.
