About Erb Mechanik AG
Erb Mechanik AG is a Swiss precision mechanics company based in Oberdiessbach in the canton of Bern. The company manufactures technical machine components from aluminium, steel and plastics as well as the high-performance plastic PEEK. The manufacturing processes include CNC milling (3- and 5-axis, including 3D freeform surface machining), CNC turning including multi-axis turn-milling, and additive manufacturing. The specialty lies in the production of high-quality individual parts, prototypes and small to medium-sized series. Services also include assembly, marking, measurement reports, and surface treatments such as anodizing and electroless nickel plating via partner companies. Customers come from among others the medical technology, mechanical engineering, automation, metrology, solar, automotive, watchmaking and pharmaceutical industries. The company was founded in 1978 and operates according to ISO 9001:2015. Rush orders are enabled by short communication channels.
