What Bolley GmbH does

Bolley GmbH & Co. KG is a family-owned German precision-manufacturing company headquartered in Prutting, southern Bavaria. The firm manufactures high-precision components — individual parts, small series, and complete assemblies — primarily for the aerospace, medical technology, and automotive industries, with additional activity in mechanical engineering, tool and die making, metal construction, and qualified materials trading. Its customer base includes major European aerospace OEMs and Tier-1 suppliers such as Airbus Defence and Space, Airbus Helicopters, ASTRIUM, Premium AEROTEC, and MT Aerospace, with whom it maintains long-term partnerships anchored by DIN EN 9100 aviation certification (held for over 20 years) and BDLI membership.

The company's production capability spans 5-axis and 3-axis CNC milling, CNC turning with driven tools and bar feed, state-of-the-art TIG/MIG/MAG welding, sheet metal cutting and forming up to 3 meters, and GRP/CFRP composite processing using the latest CNC machinery. It processes a broad materials range including aluminum, titanium, steel, copper, Rohacell, Ureol, Teflon, glass-fiber reinforced plastic (GRP), and carbon-fiber reinforced plastic (CFRP). Modern CAD/CAM and metrology systems enable on-site digitization and high-precision inspection. The firm operates with 25 employees, is registered as a GmbH & Co. KG partnership at Amtsgericht Traunstein (HRA 9907), and remains under founder-family ownership with founders Fritz and Ludwig Bolley still active alongside the next generation (Klaus, Fritz jun., and Robert Bolley).

Commercially, Bolley operates as a B2B contract manufacturer using direct, relationship-driven enterprise field sales targeting aerospace and automotive OEMs and Tier-1s in Germany and broader Europe. Revenue is generated via project-specific quotes on individual parts, molds, assemblies, composite components, and series production runs, supplemented by qualified materials trading. Pricing is non-public and varies by part complexity, material, volume, and certification requirements; the firm has no public tickers, no funding rounds on record, and no marketplace or channel-partner distribution model. Marketing is limited to a bilingual German/English website and the prominent display of industry certifications.
