HA-CO Group: A group with a goal

personal - competent - trustworthy

Haudenschild AG was founded in 1980 in CH-Rapperswil-Jona by Willy Haudenschild as a trading company with focus on coupling and linear technology. In 2002, it was taken over by Werner Haudenschild, and the product range was steadily expanded to include drive technology. In 2006 own office, warehouse and production facilities of just over 1400m2 were acquired in CH-Altendorf.

The further development to Haudenschild Holding AG took place in 2013 with the purchase of HA-CO in D-Kleinwallstadt. This was followed by HA-CO in A-Traun and in the course of this, Haudenschild AG in CH-Altendorf was renamed HA-CO Motion AG. Growth was steadily advanced with HA-CO Carbon in D-Wallerstein. On the one hand, this continuously increased the product range and, on the other hand, offered the opportunity to expand sales markets for all. Today, the HA-CO Group comprises a staff of approx. 80 employees across all 4 locations.
