Focus on automation

X-CELL LRA: Process automation at ZELTWANGER LTA

All-in-one with the automated X-CELL

Integration of laser technologies is our area of expertise. This includes welding, labeling, cutting, marking, and other applications. We use our knowledge to integrate other processes in addition to lasers – if possible, in the same system. Whether it’s screwing, assembling, or testing – we are leaders when it comes to combining important processes.

Scalable factory

Incremental investment



X-CELL LRA: Laser robot applications

The X-CELL LRA is our scalable and modular standardized machining cell that facilitates a variety of automated processes – everything in one system. It is particularly geared towards assembly processes, laser applications, and test procedures for quality assurance.

The advantages go beyond the laser and light-resistant housing. Multiple X-CELLs can be linked together or scaled cell by cell so that the processes can be adjusted step by step according to demand and increasing production quantities.

The X-CELL WB from ZELTWANGER for automated loading of CNC milling machines

X-CELL MED: Fully automated laser system

The fully automated system can mark medical devices, instruments, and packaging easily and completely safely (laser marking, black marking, annealing). This can help you to comply with UDI marking requirements and the requirements of HIBCC, GS1, and ISBT.

Various configuration options give manufacturers in medical technology plenty of free reign in order to adapt the technology to their conditions.

We support you

Because leak testing processes are complex, we don’t just sell generic leak testing devices. We plan and implement overall concepts that are based on the requirements of our customers. We are helping you to take leak tightness to a whole other level with a new device series with many unique features.

We start all processes by analyzing feasibility and parameters, then planning preliminary tests and adaptations, and finally passing on all the necessary expertise onto you in training courses and workshops.

The ZED device family for leak testing from ZELTWANGER

Flexible leak testing processes with the ZED family

Alongside our extraordinary process knowledge, our highly modern devices play a major role in the success of our leak testing concepts. The ZED device family offers standardized, adaptable solutions for a wide range of requirements.

We are the only provider worldwide that has designed a modular measuring concept. With the ZEDcore plug-and-play measuring module, our air leak testing meets the highest industrial requirements because you can exchange our measuring module yourself in just one minute for upcoming calibrations or any repairs.

Only ZELTWANGER offers you a network of all devices with the Internet of Things (Industry 4.0) via our standard OPC UA interface.

ZEDcell for leak testing with detection gases

When you need to be more precise: Leak testing with detection gases

The ZEDcell is our standardized, robot-controlled system which you can use to locate even the smallest leaks with detection gases using the sniffer method. This can be used, for example, to locate leaks in battery packs for electric cars with the highest accuracy.

ZELTWANGER LTA – our expertise

Our expertise results from the fruitful combination of German engineering, American ingenuity, and a high level of customer focus. Our work is characterized by technical expertise and our passion for developing ideas for future challenges. That is why we can guarantee the best possible solutions and keep our promises to our customers.
