Otto Hofstetter, Owner and General Manager


Otto Hofstetter AG in brief and to the point.

We are an internationally leading mould and die maker and 100% family-owned. The injection moulds developed and manufactured by us are acknowledged as first-class products by the global PET and packaging industry. Enterprises all over the world rely on our Swiss-made moulds.

99.8% of our moulds
are exported.

To this day, all our products are made at our headquarters in Uznach, and every one has a typical Swiss finish of the highest quality. Each mould is subjected to thorough tests under production conditions before it leaves our factory. Service points in many countries and mobile service technicians enable us to react quickly should customers require our assistance.

Team players at work.

As is typical for many Swiss companies, the management are personally involved in the day-to-day running of the company. Short communication paths and conscientious employees ensure efficiency and quality from the development phase to the manufacturing process, right up until the point that the injection mould is put in operation. Every day, our 200 employees and 23 trainees strive to satisfy our customers’ demands. In the interests of capacity and flexibility, we produce in two shifts and certain stages of our production process are fully automated.

CEO Otto Hofstetter on values, “made in Switzerland” and Innovation.



Deeply rooted in Switzerland, right from the beginning.

Ever since the foundation of our company, we have held on to our location in Switzerland, and we have good reasons for doing so. The Swiss education system allows us to find the skilled workers and young people with a thirst for knowledge that we need. The combination of their professional competence and typical Swiss mentality results in products and services for which we are known the world over. This is how it is today and how it will be for many years to come.
