“Truffles are my private passion, your assignment is my professional one”

Story Trueffel

The hands are digging in the slightly moist, chalky soil. The dog has picked up the scent. This is the moment when your pulse races, routine goes out the window and the excitement builds. How has the truffle developed?

No job, no product is the same. The art of transforming the customer’s needs and requirements into a functioning product, this is the art we pursue. We love the excitement we experience when the first component leaves the machine.

Herbert Lendi grows truffles. This is a task that necessitates finesse, precision and a high level of understanding of the requirements. These are characteristics that we adapt at the Federtechnik Company since the parallels between our projects and truffle cultivation are self-evident.

The Federtechnik Company – Past and present



On 29 December 1927, 16 shareholders subscribed for 70 shares and established Federnfabrik und Apparatebau AG in Kaltbrunn. In early 1928 the company started producing extension and compression springs using the plant and equipment recently acquired in Ebnat-Kappel.

The plant of the Ricken Tunnel company was used as the company’s location.


In 2007, after 60 years of producing components in Obermühlestrasse, the executive board decided to relocate the entire production to the newly acquired factory building in Benknerstrasse 54.

Today Federtechnik Kaltbrunn + Wangs uses state-of-the-art machines to develop and produce components on a total surface area of 17,000 m2.



In 1936 Federnfabrik employed 12 staff and in 1940 this figure increased to 33 employees. A good level of operation and pleasing operating results prompted the supervisory board to take on a major construction project. Following comprehensive enquiries, the nearby location of Obermühle in Kaltbrunn was chosen.


In February 2008, the owner of renowned Egli Federnfabrik AG in Dübendorf decided to sell the entire share capital to Federtechnik Kaltbrunn AG. With this merger, the Federtechnik Company expanded its expertise, particularly in the field of laser technology.

A team of 250 experienced and motivated specialists ensure unlimited possibilities in spring technology!


In 1947 production in Obermühlestrasse began. A constant level of growth enabled the company to continuously modernise and expand its machinery.  A mere ten years later (1957), Federnfabrik had increased its staff to 100 employees.


On 01/03/2011 Federtechnik Kaltbrunn AG acquired the majority of shares in the well-known and internationally active Feinstanz AG Rapperswil-Jona, which has been manufacturing high-precision metal components for more than 50 years with approximately 70 staff. Feinstanz AG has comprehensive expertise in the fields of fine blanking und metal forming technology at the highest level.


In 2004 Federnfabrik und Apparatebau AG took over Straub Federtechnik in Wangs and has since been producing components under the name of “Federtechnik Kaltbrunn + Wangs” on two sites with a total of 210 employees. A further milestone was the obtainment of the ISO-TS 16949 certificate – the gateway to the automotive industry.


On 30/10/2015 the supervisory board of Federtechnik Kaltbrunn AG decided to relocate the production from the Wangs site to the Kaltbrunn parent company. This constitutes another measure to secure the competitive capability in the international market.
