Smart solutions for automation

Our automation solutions for assembly and testing systems stand out for their intelligent modularity and high level of standardization. For both our pre-engineered systems (e.g. X-CELL) and custom designs, maximum efficiency is always the focus. The reason for this is that sustained customer value can only be provided if the systems have a high level of availability and are seamlessly integrated into existing production environments.

Extensive past experience has shown that the processes used allow us to achieve the fastest development cycles and a high level of process reliability at a very attractive price. Our modules can be used adaptively as stand-alone solutions or integrated into an existing process chain as needed.

ZELTWANGER - Automation


The expertise we have acquired in years of project experience has given us a solid grasp of numerous processes. Whether pre-engineered or custom designed – we provide the best automation solutions for a wide variety of tasks in the areas of leak testing, assembly, function testing, laser welding, and laser engraving.

That said, leak testing is one of our core technologies. ZELTWANGER Group has conducted research, development, and training in this area for many years now. This has resulted in highly specialized, field-tested systems and our own extensive line of devices.

Our outstanding expertise includes the following assembly applications:

  • Joining
  • Press Fitting
  • Screw Fitting
  • Gluing
  • Palletizing
  • Caulking
  • Riveting

We offer highly effective solutions in the field of function testing, particularly regarding measurement capacity. Our focus here is on the following testing processes:

  • Mechanical testing
  • Electrical testing
  • Pneumatic testing
  • Wet testing
  • Dry testing
  • Flow measurement, torque measurement
  • Ease of operation testing

We are on the cutting edge of technology in terms of laser welding. We achieve the best results and optimal process reliability even with highly demanding material combinations, including the processing of:

  • Metal
  • Plastic
  • Plastic/metal

Our robotics-based automation solutions for laser engraving stand out for having the highest quality and using the highest-grade components. This allows us to ensure a perfect result for each and every part.

Whether for welding or engraving, we only source our lasers from well-respected, quality suppliers, as with all our components. We have a long-standing partnership in development, technology, and projects with these suppliers.

ZELTWANGER - Processes


We offer pre-engineered solutions based on tested systems. The expertise acquired by the ZELTWANGER companies over the years has enabled them to provide pre-engineered devices that merely need to be adapted to the customer’s particular needs. In order to maximize customer value, we focus heavily on a high level of availability, measurement capacity, and intelligent modularity for all of our system designs. This allows a wide variety of processes to be linked efficiently, and our systems are reliably integrated into existing production environments.


Parts can be quickly and reliably assembled, processed, tested, and laser welded and engraved using the robotics-based processing cell X-CELL. The working chamber is closed with a laser barrier for laser engraving. Thanks to its modular design, X-CELL can be implemented as a partially or fully automatic, flexible, stand-alone cell or integrated into an in-line system. A variable number of processes can be integrated or individually configured. This space-saving, articulated robot with six axes accurately guides parts weighing up to ten kilograms to the desired process. Intelligent control software ensures additional process reliability and optimal integration in the existing production network.

X-CELL’s dimensions and process tooling can be configured according to the customer’s specific needs. Features of the rack are also scalable, such as the position of the control panel and the feed and discharge for parts. Standard components ensure delivery times are short. Simple, button-activated program settings facilitate quick tool conversion for part changes. It is also no problem to have continuous production with a function for changing tools or grippers for different part types. In the process, the various geometries are automatically identified and further processed.

X-CELL can be readily accessed and saves space. The upper section can be closed with laser-proof shutters. The lower portion has removable doors that provide easy access for maintenance purposes.
