Expertise, longevity, and reliability – ZELTWANGER Automation structures itself around and operates in individual customer and product expert teams as closely to customers as possible.


From the L-CELL to the X-CELL. Thanks to an extended range of applications, it can now be used to automate a variety of combined processes, from lasers and assembly to automated leak testing applications.

ZELTWANGER founds the ZELTWANGER Leak Testing & Automation LP business division in Charleston, US. This allows the company to position itself as a partner on the American continent in the areas of automation and leak testing.

The expansion of ZELTWANGER Maschinenbau in Tübingen means that all production areas can be combined under one roof. This creates more space for innovation and development at the two Dußlingen locations.

The automation and leak and functional testing business divisions are physically separated in Dußlingen, even though they work together more and more in terms of content and technology.


ZELTWANGER Automation automates machine tool loading with the X-CELL WB. Customers can receive a quotation based on their requirements live via an online configurator.

ZELTWANGER Automation develops the X-CELL LRA specifically for robot-based laser applications. At the same time, the X-CELL MED, which is specially equipped for UDI labeling in medical technology, is created.
