Rüetschi AG

What Rüetschi AG does

Rüetschi AG is a Swiss bell foundry and church technology company headquartered at Rain 44, Aarau, claiming origins dating to 1367 and recognized as Switzerland's oldest continuously operating manufacturing company. The core business centers on Kirchentechnik (church technology), encompassing bell casting, tower clock systems, sound optimization, restoration, automation, and workplace safety for churches and public buildings. Through wholly-owned subsidiaries, the firm has expanded into adjacent verticals: Syneos GmbH (event-oriented building automation, founded 2019), Kunstbetrieb (art production and restoration, acquired 2019), Algisa (aluminum precision casting for vehicles, machinery, and aerospace, acquired 2019 from ABB), Schmiede zu Aarau (blacksmith forge, acquired 2017), and Jacob Mäder AG plus Hans Diethelm (tower clock factories acquired 2005-2007). Operations are coordinated from the historic foundry site at Rain in Aarau (active since 1607) and a tower clock manufacturing location in Andelfingen.

The technical foundation combines 650+ years of foundry expertise with multiple casting methods (sand, vacuum, permanent mold, lost-wax) and modern capabilities including in-house 3D scanning and printing, static calculation, and metal processing. Rüetschi is co-initiator of ECC-ProBell, the European Competence Center for bell research at Hochschule Kempten, Germany, providing proprietary scientific calculation software, the "Musikalischer Fingerabdruck" (musical fingerprint) vibration analysis for early damage detection, and engineered ProBell bell clappers using double-pendulum physics. The firm filed the first Swiss patent for an electric bell ringing device in 1906 and was awarded the Aargauer Heimatschutzpreis heritage protection prize in 2023.

The business operates as a project-based engineering services and specialty manufacturer under nearly 100% foundation (Unternehmensstiftung) ownership. Pricing is quoted in Swiss Francs, ex-works, with 30-day net payment terms and 8.1% VAT. Revenue streams include one-time product sales (bells, bell frames, tower clocks, automation hardware), professional services (engineering, installation, maintenance, restoration), and ongoing service contracts. Distribution is direct field sales across Switzerland with technicians dispatched to customer sites, supplemented by an international reference project (the Swiss Glockenspiel in London maintained for Switzerland Tourism). Customer segments span churches, public municipalities, artists, private clients, and industrial buyers via Algisa.
