Company History

Franziska Tschudi Sauber, Delegate of the Board of Directors and CEO since 2001, will step down as Chairman of the Board of Directors and focus on the strategic management of the Weidmann Group. In May she hands over responsibility for operational management as CEO to Maximilian Veit, CFO and member of the Executive Board since 2014.



In March 2017, Weidmann Medical Technology North America relocates its production site in record time from Auburn (USA) to Saltillo (Mexico). The production site reaches 35,000ft2 and offers clean rooms ISO class 7.



The Medical Business Unit, created in 1998, becomes Weidmann Medical Technology AG, an independent company within the Weidmann Group. The Automotive and Industrial Division is sold to the Techniplas Group, an American company.


Expansion of the production site of the Medical Division in Bad Ragaz, Switzerland.  The surface of the clean-room production is doubled at this point.


Franziska Tschudi-Sauber takes over the Executive Management of the Weidmann Group from her father.


Acquisition of Bruwag AG, Bad Ragaz, Switzerland. Construction of a new manufacturing site with clean-room production for the Medical Division. In 2006 the company is integrated into Weidmann Plastics Technology AG in Rapperswil.


Weidmann Plastics Technology successfully replicates microstructures (nanotechnology) in medical components for analytic and diagnostic applications (Lab On A Chip).


Dr. Felix Tschudi-Hubacher assumes control of the company from his Father.  Tschudi & Cie AG is integrated into Weidmann. Convinced that exports from Switzerland alone cannot cover the growing world-wide customer demand, Felix Tschudi begins an ambitious program of international expansion of the Weidmann Business Unit High-Tension Insulation (later Electrical Technology).


Hans Tschudi travels to the USA to take possession of the first injection-molding system.


Due to the collapse of exports of high-tension insulation material due to the onset of the Second World War, Weidmann survives thanks to its activities in Plastics Technology. Plastic components, considered replacement materials, are especially sought after for gun-barrels and telephone housings.


Jean Tschudi‘s son Hans Tschudi-Faude, a paper engineer, is entrusted with the necessary restructuring of the company. He positions H. Weidmann AG as a first-class supplier of specialty boards based on cellulose, and components for the transformer industry (ultimately Weidmann Electrical Technology). He also begins with the production of die-formed parts in duro- and later thermo-plastic resins for industrial applications (ultimately Weidmann Plastics Technology).


On the edge of bankruptcy, the company is taken over by a financial consortium led by Jean Tschudi-Klaesi, the owner of a small, exclusive board manufacturing company in Ennenda, in the Canton of Glarus. Tschudi & Cie AG manufactures specialty board material for non-electrical applications, especially matrix boards for pressure plates for use in rotational pressure systems.


Heinrich Weidmann acquires the old, water-powered City Mill in Rapperswil, Switzerland. He establishes a press-board and carton company and begins manufacturing insulation materials for the nascent electrical technology industry.
