The global situation in terms of lightweight design strategies using various materials is characterized by an increasing demand for flexible manufacturing technologies for sheet-like materials and semi-finished parts that enable efficient solutions, predominantly in the automotive and aircraft industries.

The cw remote laser processes, which can be implemented by means of the prototype system, are profitably used in multi-material lightweight constructions for direct thermal joining of metal with thermoplastic fiber-reinforced compounds.

Large-area structuring with high power lasers can replace wet chemical surface pretreatment and at the same time ensures good adhesion for even bonding.

Thanks to new brillant high-performance laser beam sources and suitable system technology, it is now possible to realize quasi-simultaneous laser processing in large working areas (up to 1 m²).

In automotive engineering, elastomer-based EPDM cavity profiles for sealing passenger areas are state of the art and widely used in industry.

To use thermoplastic fiber-reinforced composites in large series production, suitable reproducible bonding techniques are also needed.

Aluminum materials and other metals with an anodic oxide outer film, need anticorrosive and inhibiting oxide layers of sufficient thickness and density.

Dielectric elastomer actuators are electrically active polymers and are not only used as actuators, but can also function as sensor systems or energy converters.

Contact tabs of aluminum conductor sealing areas must be pre-processed to guarantee a strong adhesive bond, tightness and long-term ageing resistance.

Within the scope of a PROINNO research project, thousands of glass-metal and glass-glass bonded joints were produced, aged and tested.

A compact and flexible heating tool was designed and built by using a quickly tiltable mirror, in combination with a direct irradiated diode laser.

Particularly complicated part geometries demand significantly enhanced production accuracy, as well as reproducibility of the cutting, handling, stacking and compounding processes.
