About Borschberg + Käser AG
Borschberg + Käser AG is a Swiss family-owned business founded in 1947 with around 42 employees in Wettswil am Albis (ZH), specialised in industrial sheet metal processing. It manufactures individual parts, prototypes and complex sheet metal assemblies for customers in the metal and mechanical engineering industries as well as apparatus, vehicle, aircraft and rail vehicle construction. The value chain includes CNC laser cutting and punching (sheets up to 3000 x 1500 mm; laser up to 25 mm steel, stainless steel and aluminium), bending up to 3000 mm, welding (MIG/MAG/TIG/CMT, robotic welding to EN 15085 CL2, manual and AGL laser welding), bonding to DIN 6701-A3, deburring, grinding, straightening, shot blasting as well as machining, design with 3D CAD and assembly including kitting and packaging. As an EN 1090 certified company, load-bearing steel structures up to EXC2 are also manufactured. Suppliers such as SBB, Deutsche Bahn (Q1 certificate), Siemens, Schindler and Stadler Rail rely on the process quality certified to SN EN ISO 9001:2015.
