About BIEG
Badische Industrie-Edelstein Gesellschaft mbH (BIEG) was founded in 1948 and manufactures precision parts for optics, medical technology, metrology, sensor technology, and mechanical engineering. The portfolio includes plan optics such as plan discs, stepped windows, planovals, and plan convex lenses made of sapphire and ruby, components like roller bearings, nozzles, guides, and valve parts, as well as precision axes, shafts, thin-walled turned parts, and CNC-machined small parts from carbide, metal, and plastic. Production is scalable from the prototype phase to stable series production, supplemented by assembly of subassemblies and first-article inspection according to PPAP or customer-specific test plans, including measurement reports and test evidence. Manufacturing is also done according to special drawings, with feasibility, tolerances, and material selection clarified in technical engineering. The company is located in Elzach in Baden-Württemberg and supplies customers in the German-speaking region as well as internationally.
