The WEIDMANN History

From 1877 to present
1877V1 1877
Heinrich Weidmann acquires the old water-powered town mill in Rapperswil, Switzerland and establishes a pressboard and cardboard factory. He starts supplying insulating materials to the still young electrical industry.
1914V1 1914
Heinrich Weidmann dies without a successor. His company is taken over by management and townsmen of Rapperswil and transformed into a joint stock corporation ("H. Weidmann Aktiengesellschaft"). The ailing company acquires "Grüzengut", 4 hectares of land in Rapperswil, and builds a modern industrial production and office complex.
1923V1 1923
Close to bankruptcy, the company is acquired by a financial consortium under the leadership of Jean Tschudi–Klaesi, the owner of a small board mill, from Ennenda in the nearby Canton of Glarus. Tschudi&Cie AG produces specialty boards for nonelectrical applications, in particular stereotype matrix boards used in rotary printing.
1925V1 1925
The necessary restructuring is entrusted to Jean Tschudi's son, paper engineer Hans Tschudi–Faude. He positions H. Weidmann AG as a first class supplier of cellulose based specialty boards and components for the power transformer industry (WEIDMANN Electrical Technology), and later on moulded parts for industrial application from thermosetting material and thermoplastics (WEIDMANN Plastics Technology).

1930-48
Plastic resin compounds, in particular Bakelite, have become fashionable. WEIDMANN is one of the first companies in Switzerland using this base material in compression moulding to manufacture machine parts for the spinning and weaving industry.

First production of insulation components from calendered pressboard. In 1937, Hans Tschudi invents "Transformerboard" (hot press dried insulation board mainly used for transformers).

1939-45
During the Second World War, when export of high voltage insulation collapses, WEIDMANN survives thanks to its booming Plastics Technology, producing components from rifle shafts to housings for the domestic telecommunications industry.

1948
Hans Tschudi travels to the USA to buy the first injection moulding machine.
1952V1 1952
An important breakthrough in Electrical Technology is achieved by installing WEIDMANN's first large size (3x6m) Transformerboard (T IV) machine in Rapperswil, Switzerland.
1968V1 1968
Dr. Felix Tschudi-Hubacher assumes management responsibility from his father. Tschudi&Cie AG is integrated in the WEIDMANN organization.
Convinced that export alone will not satisfy growing customer demand, Felix Tschudi starts an ambitious international expansion program for WEIDMANN’s high voltage insulation (ELECTRICAL TECHNOLOGY) business.
1970V1 1970
Procelis SA, Bourgoin-Jallieu, France (fabrication of insulation components), today WEIDMANN ELECTRICAL TECHNOLOGY S.A.S,  joins the WEIDMANN organization as Joint Venture/licensing partner and is finally acquired in 1976. Site was transformed into a conversion center in 2011.
