On 1 May 1957, Hans and Ruth Jossi founded the company “Hans Jossi, Präzisionsmechanik” in Frauenfeld. With its total devotion to realising challenging engineering concepts, the young company gained the trust of several large and medium-sized companies from all over the region. As its range of manufacturing services expanded, the business grew steadily.

As a result of major orders from the power plant sector, the company built its own premises with scope for modular expansion in Islikon in 1964; the premises tripled in size in 1973. The growing demand for manufacturing services in the medical technology sector led to further expansions of the building in 1983, 1992 and 2001. An additional assembly site in Wängi was opened in 2009. Nowadays, the company has some 8,000 m2 of floor space at its disposal.

“JOSSI Holding AG” now comprises the legally independent companies “JOSSI AG”, with its core business of systems realisation, and “Jossi Orthopedics AG”, a manufacturer of components for orthopaedic implants. These companies employ a total of 150 experts, including 20 apprentices. The quality-related organisational elements of both companies are certified to ISO 9001 and ISO 13485.
