Evosys reported strong interest in its laser plastic welding portfolio during K 2025 in Düsseldorf. At its booth, the company highlighted the compact EvoWeld Mini in a wood housing, the latest EvoWeld Generation 2 platform, and the Evo 0800-TD process module. Visitors engaged in detailed technical discussions on process control, part handling and integration, reflecting demand for flexible solutions that combine productivity with material efficiency. The wooden version of the EvoWeld Mini was used to emphasize the sustainability aspects of laser plastic welding, while an integrated absorption tester on the station demonstrated how the optical behavior of joining partners can be verified directly at the equipment. Alongside product demonstrations, Evosys focused on shorter delivery times, modular configurations and easier line integration across its range, and showcased a retrofit path for two-stage welding that can be deployed on existing machines with pneumatic clamping systems.
EvoWeld Mini and system generation 2
A trade fair highlight was the EvoWeld Mini configured in a wooden housing. Beyond its visual impact, the station integrated an absorption tester, turning the exhibit into a practical demonstrator for assessing joining partner behavior prior to welding. According to the company, this drew sustained attention at the booth and served to underline the role of optical characterization in achieving stable results in laser plastic welding.
The EvoWeld Generation 2 platform was another focus area. Continuous development and an optimized design target higher welding quality while aiming for shorter delivery times. The system is available at short notice and can be adapted to project needs with either manual or automatic loading and unloading, enabling flexible deployment in prototyping or series environments.
Evo2Step process, retrofit and large-format options
Evosys demonstrated a retrofit kit for the Evo2Step process on a standard machine during live welding. The kit combines additional hardware with a sequence control designed for existing equipment, allowing the Evo2Step variant to be integrated on machines equipped with pneumatic clamping. In this configuration, two absorbent components with a footprint of up to approximately 100 x 100 mm can be welded efficiently and with high quality in a two-stage process on almost all Evosys machines.
For larger components, new Evo2Step machines are available with up to 2.8 kW laser power, working areas up to 2 x 2 m, servo-electric clamping systems and further options. Among the features is, for the first time, the ability to determine plastic absorption at 980 nm. Because heat absorption behavior of the two joining partners is critical for process control in the two-stage method, the absorption test function facilitates checking and accurate comparison between different parts.
Evo 0800-TD integration concept
Evosys also presented the continued development of the Evo 0800-TD. The compact control technology is now housed in space-saving 19-inch racks, which simplifies integration into existing production lines and reduces space demand because a separate control cabinet is not required. A stand-alone kit with an operator interface enables manual operation, useful for process development and sample part production. The process module can later be integrated into a fully automated line, allowing the accumulated process know-how to be transferred directly to series manufacturing.
"K 2025 was a complete success for us," said Managing Director Holger Aldebert. "The high number of visitors and the great interest in our innovations show that our solutions are striking a chord with the industry. We are particularly pleased that sustainability and efficiency are becoming increasingly important to our customers, this is exactly where our products come in."
