Otto Hofstetter AG marks 70 years of innovation and family continuity
This year, Swiss mould-making specialist Otto Hofstetter AG celebrates its 70th anniversary – a milestone that reflects decades of innovation, precision engineering and international success. Founded by Otto Hofstetter Sr. in 1955 as a small workshop in Uznach, the company has steadily evolved into a leading global manufacturer of high-performance injection moulds, particularly in the field of PET preforms and thin-wall packaging.
Throughout its history, Otto Hofstetter AG has demonstrated a strong pioneering spirit. From producing its first thin-wall packaging moulds in the early 1960s, to developing the world’s first PET preform moulds in 1977, at a time when no one else dared, the company has consistently embraced technical challenges. With the creation of the holistic Otto Systems brand and the launch of its own PET injection moulding machines, the company took a bold step towards vertical integration, securing independence and long-term competitiveness.
The 70th anniversary held in June was marked with a campaign that looked back on key milestones, celebrated the achievements of its employees, and set the stage for the future. A special highlight was the introduction of the third generation of the Hofstetter family: Lea Hofstetter, daughter of Otto Hofstetter Jr., has joined the company and is gradually taking on a more active role. Her involvement signals the continuation of family leadership and a clear commitment to long-term development.
With around 200 employees and 23 apprentices, the company places strong emphasis on training and talent development – a commitment that has earned it recognition as a “TOP training company” in Switzerland. The opening of the new TechCentre in 2024, featuring multiple assembly and demonstration stations, further underlines the company’s forward-looking approach.
