PWB

What PWB does

PWB AG, founded in 1981 and headquartered in Altstätten, Switzerland, is a precision CNC manufacturing company operating as a subsidiary of the Polygena Gruppe. The company delivers end-to-end mechanical manufacturing under one roof, spanning development support, prototyping, CNC turning, CNC milling, and 5-axis turn-milling using CAD/CAM programming on Mastercam, complemented by in-house and partner surface treatments (anodizing, hard anodizing, black coating, hard chrome plating, polishing, burnishing), cleaning, assembly, quality assurance, packaging, and logistics. Its material expertise covers aluminum, stainless steel, titanium, brass, Dispal, and specialty alloys, including aerospace-grade stock for vacuum and cleanroom applications.

The company serves six vertical markets: Optical Industry, Medical Technology, Aerospace & Space, Semiconductor Industry, Mobility, and Plant & Machine Construction. Core product offerings include CNC precision turned parts (Drehteile), precision milled parts (Frästeile), turn-milled parts (Drehfrästeile), and complex assemblies (Baugruppen) ranging from titanium and multi-material assemblies to helium-tight and custom optical subassemblies. Cleanroom assembly, particle-free packaging, and vacuum-compatible manufacturing are positioned for semiconductor and aerospace customers. PWB holds ISO 9001 and ISO 13485 certifications, both successfully re-audited in June 2026, supporting regulated-industry qualifications and traceability requirements.

PWB operates a B2B project-based revenue model with quote-based pricing scaled to part complexity, material, tolerances, surface treatment, lot size, and documentation requirements. The go-to-market is direct enterprise sales through named sales managers (Stefan Fischbacher, Ahmet Cerimi), supported by technical content marketing, LinkedIn and YouTube presence, industry events (ILA Berlin, Space Tech Expo Europe), and association memberships in Swissmem and the Swiss Space Industries Group (SSIG, joined 2026-01-30). PWB Academy trains Polymechaniker EFZ and Produktionsmechaniker EFZ apprentices, partly through collaborations with ETH Zurich's AMZ Racing and DHBW Ravensburg's GFR Global Formula Racing. The company is privately held, with no disclosed funding rounds, acquisitions, or revenue figures.
