Evosys meets these challenges with an innovative process for laser welding transparent films that does not require the use of additional absorbers. This advanced process not only enables plastic films to be joined efficiently, but also offers a wide range of customization options for different design and tightness requirements.

Laser welding of transparent films

Our latest process enables the laser welding of two transparent films, completely without the use of additional absorbers such as carbon black, which is typically used to absorb the laser energy. The laser beam heats the two plastic films precisely at the desired joint. Pressing them together in the heated state creates a material bond. The chemical composition of the materials is completely retained. This is a decisive advantage for applications with the highest demands on purity and material compatibility. Typical areas of application can be found in medical technology.

Highest seam quality

The process impresses with clean, particle-free weld seams with high mechanical strength and reproducibility. Even sensitive or thermally critical materials can be joined reliably. The precise heat input effectively prevents thermal damage to the material.

Variable seam design for individual requirements

A special feature of our technology is the highly variable adjustability of the weld seam width, from the finest precision seams to wide, flat joints. This means that different design specifications, mechanical requirements or tightness requirements can be optimally implemented.

Complex geometries and large formats

Our system technology not only enables the welding of complex contours and 3D components, but also large film formats, with consistently high precision and process stability. This opens up a wide range of possibilities for functional and high-quality product solutions.

Contract manufacturing with the latest laser technology

Benefit from our many years of experience in the field of laser joining technology and our modern machinery. We offer you laser welding as contract manufacturing and support you from the initial idea through the design and procurement of your components to series production.

By outsourcing production processes to a specialized partner like us, you not only save on investments in machinery and personnel, but also gain planning reliability and speed of response. Our expertise enables short throughput times, high process reliability and consistently high quality. Even with fluctuating quantities. This allows you to concentrate fully on your core competencies while we take over the joining of your components efficiently and reliably.

We will be happy to advise you on your specific application.
