Wolfensberger AG

Since Jakob Wolfensberger established his eponymous foundry in 1924, this family-owned Swiss company has continuously adapted to changing market needs. During its over 90-year history, Wolfensberger has steadily evolved its casting techniques, material variants, and production processes.

Today, it offers around 100 types of cast steel and cast iron, two casting processes—sand and ceramic precision—as well as specialist machining of ready-to-mount castings at its two locations.

Local roots, international outlook: based in Bauma, near Zurich, Wolfensberger produces custom-engineered castings for a multi-industry customer base in Europe, Japan, Korea, and India. To meet the changing demands of customers and markets, the company relies on close consultation as well as the highest quality standards. As a result, Wolfensberger is able to develop specially tailored and ready-to-mount castings not only for manufacturers of commercial road vehicles, rolling stock, ships, aircraft, and spacecraft but also for companies in the construction, food, energy, and chemical industries.

Over the past decades Wolfensberger AG has developed into an established company with an excellent international image. In order to further expand this market position and to meet our high requirements with respect to innovation and quality, we need a strong and entrepreneurial partner. Fidelium fully meets these criteria, allowing us to set the course for a continued successful and growth-oriented future
