Precision is Tradition - for 67 years!

Arnold Ehrat AG was founded in 1953 and since then has been involved in the manufacture of precision components and ready-to-assemble assemblies. Our customers appreciate the precise quality of our products and services as well as the flexible order processing.

In July 2011 Walter Pfenninger takes over the management of Arnold Ehrat AG. At the beginning of 2015 Walter Pfenninger buys the company from the former managing director Rolf Ehrat, son of the founder Arnold Ehrat.

Since 2008, Arnold Ehrat AG has been training apprentices as polymechanics and production mechanics. We are proud to offer the apprentices a varied apprenticeship and to give them the best possible start in the professional world. Since summer 2018, our former apprentice Dajana Näckel (graduation in 2015) has been in charge of the production. She completed her second apprenticeship as a production mechanic with us and was awarded the “Stiftepriis” from Pestalozzi with the highest mark of 5.4 in the Canton of Zurich. Joel Decarli, who completed his apprenticeship with us in 2016, has since worked for us as a permanent employee and in the summer of 2018 he took over the function of instructor. He is currently responsible for 3 apprentices.

The family-run company Arnold Ehrat AG attaches great importance to precision and high quality in production. We split the thousandth with passion and are only satisfied when our customers are.


We are proud to have received the "Preferred Supplier" certificate from Besi this year. On the picture are our two assembly employees Silvia Haller (3rd from left) and Rita Pfenninger (2nd from left) and our production manager Dajana Näckel (2nd from right). Also in the picture is our managing director/owner Walter Pfenninger (1st from left) and our marketing/purchasing employee Fabienne Pfenninger (1st from right) with safety manager Gioia on their arms.

Our goal is of course to continue to deliver this performance and to receive this certificate again next year. For this we would like to thank our two assembly workers Silvia Haller and Rita Pfenninger, as well as our production manager Dajana Näckel. A big thank you goes of course also to Besi for the very pleasant cooperation and also to our suppliers, who support us at any time.
