In 2014, Gewinde Ziegler AG bought up Härterei Hertig AG.

Years of combined know-how acquired together with Härterei Hertig could be secured and 2019 the company moved to the new facility in Horriwil.

The newly introduced processes, like core and inductive hardening, allow us to perform thermal treatments of shafts with up to 10 meters in length. The result is our capacity to cover the completeb production process of our products in-house. This leading to a high degree of flexibility and know-how security for our customers.
