About EDM Plus
EDM Plus Sàrl is a specialist in micro-machining by wire electrical discharge machining and die-sinking EDM based in Le Locle in the Swiss Jura. The company was founded out of the desire to offer complementary and vertically integrated manufacturing services to customers of the parent company Chalon SA, which specializes in CNC milling and CNC turning in precision machining. The combination of the expertise of both companies enables comprehensive machining of precision parts from a single source. EDM Plus also positions itself as an independent alternative in the market for mechanical high-precision contract manufacturing, serving demanding cutting-edge technology industries. Its team of specialist experts combines more than 50 years of multi-sector experience and supports innovative projects with technical know-how in micro-machining by EDM.
