Gudo AG
Gudo AG specialises in the manufacture of fasteners, but we are generally able to meet any challenge or requirement in the field of plastic components. Our high-quality systems are used in the industrial, sports, orthopaedic, automotive and occupational safety sectors. Our fasteners are also known worldwide for their use in the helmet sector to adjust the head size.
We are also particularly strong in the field of bike racks. Whenever securing or adjusting is required, you can count on us. Our products are developed, manufactured and distributed at our factory in Lupfig – and bear the „Made in Switzerland“ seal of quality.

Company history
In 1973, the partnership “Guggenberger & Dobler” (Gudo) was renamed “Guggenberger & Dobler, Stanzerei und Werkzeugbau AG”. Two years later, on 14 July 1975, the company was entered in the commercial register as “Gudo AG, Metallwarenfabrik”. In 1995, the name was changed again, and since then it has been known as “GUDO AG“.
Owing to Gudo AG’s positive growth, an industrial site was purchased in Oetwil am See in 1981. The new factory building was commissioned in August 1988. In addition to a well-equipped production facility, plastic components were now also manufactured in-house, and a powder coating plant and a modern tool shop were installed.
In 1985, the two founders of Gudo AG parted ways, and Mr Guggenberger took over the company. In February 1990, Mr Guggenberger decided, for various reasons, to sell the company to R. Burkhart.
Gudo AG’s previously successful run was interrupted by the unexpected collapse of its main customer, Raichle AG. However, a large proportion of the losses was offset by the introduction of the new “Mega” fastener in the snowboard sector. Furthermore, the expansion into the helmet market with ratchet or twist fasteners for size adjustment has opened up a new market. Finally, the company’s leading position in the field of helmet fasteners was further strengthened by the acquisition of the production and patent rights from Swock AG.
Enrico Maraffio as the new CEO
At the same time, the company entered the “car accessories” market with ratchet fasteners, a sector that has since become one of the largest and most important areas of business for Gudo AG.
The process of finding a successor to R. Burkhart began in 2010 with the appointment of Enrico Maraffio as the new CEO. On 22 June 2012, Gudo AG was acquired and the share capital was transferred.







Opening of the new plant in Lupfig in 2015
At the same time, the stamping and powder coating processes were outsourced to external partners. Furthermore, investments were made in plastic injection moulding technology (two-component technology) and the focus on development activities (both customised and in-house developments) was strengthened. Continuous change also means constant further development.
