Our Business


We are proud to look back on more than 30 years of history as Siebenwurst Werkzeugbau GmbH in Zwickau. The company was founded by Leonhard and Christian Siebenwurst at the historic automotive location Zwickau in 1991. Both entrepreneurs are experts of tool manufacturing and mold construction and also run the family owned company Christian Karl Siebenwurst GmbH & Co. KG Modell- und Formenbau in Dietfurt, Altmühltal.
At the beginning 55 employees – expert, who learned tool manufacturing from scratch in the Sachsenring-Trabant plant - were available. The newly founded company Siebenwurst Werkzeugbau GmbH was able to stand its ground with high quality handcraft, enthusiasm and dedication and finally reached to acquire numerous new customers within the automotive industry and beyond.

This was the beginning of a continuous development - a real success story.
