Innovative manufacturing solutions are becoming increasingly important, particularly in the medical technology sector. A current example of this is an ECG monitor from livetec Ingenieurbüro GmbH, which will be manufactured in the future as part of our contract manufacturing services using laser plastic welding.
Until now, the product has been manufactured in small batches using adhesive bonding. However, as production volumes increased, this method reached its limits. In particular, the process reliability and reproducibility of the adhesive bond, as well as the reliable sealing of the housing, posed significant challenges for a medical device. At the same time, the manufacturing process needed to be designed to be cost-effective and as automated as possible for future mass production.
Together with the livetec engineering firm, we therefore developed a new manufacturing concept based on laser plastic welding. Already during the development phase, the materials used and the component design were specifically tailored to the requirements of the welding process. Subsequently, the welding process was set up and optimized as part of the sampling phase.
The first end-customer samples were successfully manufactured and proved their worth through both a stable, reproducible process and by passing all leak tests. This laid the groundwork for the reliable mass production of the ECG monitor.
Another advantage of laser welding technology is its integrated inline quality monitoring. During the welding process, all relevant process parameters are continuously monitored and documented. Components that do not meet the defined quality requirements are immediately identified and can be directly rejected. The comprehensive process documentation also supports the high standards for quality and traceability in the medical technology industry.
This project serves as an example of how existing manufacturing methods can be replaced by modern laser welding processes. Particularly for enclosures containing sensitive electronic components, laser plastic welding enables reliable, leak-tight, and automated mass production, thereby laying the foundation for cost-effective production even as production volumes increase.
Would you like to familiarise yourself with this joining process and learn more about the theoretical principles behind it? If so, we recommend the SKZ seminar ‘Laser Welding of Plastics’, taking place from 28 to 29 October in Würzburg, Germany. It provides an overview of the fundamentals and concepts of laser welding of thermoplastics.
The event is aimed at employees in the plastics processing and chemical industries, as well as those changing careers. It focuses on the following topics:
• Laser sources for plastic welding
• Materials, colourants and additives
• Principles, applications and potential of laser through-beam welding
• Principles of laser safety and innovations
Learn all about joining plastics in small groups. A number of specialist presentations by renowned experts will provide information on this non-contact process. The training course is rounded off with a practical session at the SKZ Technical Centre.
By the end of the course, you will have a better fundamental understanding of the technology and will have expanded the possibilities for your product development. This makes the event an ideal introduction for anyone wishing to familiarise themselves with the process or to deepen their existing knowledge.

With the founding of Attosys Laser GmbH in July 2026, the Evosys Group is expanding its technology portfolio to include innovative laser-based manufacturing processes for demanding applications in micro- and macro-machining. The new subsidiary, headquartered in Erlangen, focuses in particular on glass machining and the joining of different materials.
Attosys’ range of services includes laser welding, laser structuring, laser cutting, and laser drilling. A particular focus is on the hermetic joining of glass components. This includes glass-to-glass welding, glass-to-metal welding, and glass-to-silicon welding. These processes open up a wide range of possibilities for applications in medical technology, microsystems technology, and the semiconductor industry.
In addition, Attosys develops solutions for processing plastics as well as for cutting and structuring glass, metal, and ceramics. The processes used enable precise machining with little to no heat input. Depending on the configuration of the thermal process, it is possible, for example, to create rounded or sharp-edged holes in glass tubes. Ultra-short-pulse lasers, among other technologies, are used for processing. The combination of different laser technologies makes it possible to tailor processes specifically to different materials, component geometries, and requirements.
Technological advantages include hermetic joints, high seam strength, and minimal thermal stress on the components. This reduces thermal stresses and allows different materials to be joined together without the need for additional adhesives.
As a subsidiary of the Evosys Group, Attosys draws on more than 20 years of experience in laser technology, material processing, and custom machine building. This expertise forms the foundation for the development of specialized manufacturing solutions. Customers benefit from a comprehensive range of services, extending from process development and integration to automated production machinery.
Through collaboration with universities, technical colleges, and laser centers, Attosys also lays the groundwork for the continuous advancement of these processes. For more information on technologies, products, and applications, visit www.attosys.com
Evosys will be showcasing new generations of machines and live laser welding processes at Fakuma fair 2026
From 12 to 16 October 2026, Evosys Laser GmbH will be presenting innovative solutions for laser plastic welding at Fakuma in Friedrichshafen. In Hall A4, Stand A4-4306, the technology leader will be showcasing new generations of machines, tried-and-tested process modules, and measurement and testing methods for efficient, high-quality plastics processing.
The focus of the exhibition stand will be on live welding demonstrations, which clearly illustrate the capabilities of modern laser welding processes. Visitors will be able to experience both conventional through-beam welding and the advanced Evo2Step process directly on the EVO 0800-TD laser system. This will clearly illustrate how process windows can be expanded, tolerances better controlled and component quality reliably ensured.
We are also presenting our absorption test device, which enables precise analysis of the absorption behaviour along the weld path. This is a key parameter for the new two-stage laser welding process, Evo2Step. It allows different materials or material batches to be compared directly with one another. The graphical display of multiple measurement results provides an immediate comparison of different samples. If the curves differ despite the same welding contour, the causes can be attributed to differences in material. Where values deviate, the welding parameters can be specifically adjusted to ensure that the welding process remains stable and reproducible. In this way, consistently high-quality results are achieved in the laser processing of plastics.
“Our presence at Fakuma 2026 underlines our commitment to acting as a partner for sophisticated laser welding applications in plastics technology,” explains Managing Director Holger Aldebert. “Through a combination of live demonstrations, a new generation of machines and metrological support, we are demonstrating how robust, cost-effective and future-proof manufacturing solutions can be realised.”
