The TWIST® method enables the highest process speed, flexibility and strength for the laser welding of plastics

At Stand 4211 in Hall 4 of Fakuma (October 13 – 17, 2009, Messe Friedrichshafen), the Fraunhofer ILT will be presenting a novel, compact and industry-ready plant concept to laser weld plastics using fiber lasers.
Thanks to the TWIST® radiation concept, a quick, temporal and localized beam modulation forms the basis for this new laser method. Fraunhofer ILT's researchers in Aachen have developed and qualified TWIST® – “Transmission Welding by an Incremental Scanning Technique” – an innovative process to weld plastics.
When compared to standardized laser plastic welding plants, this new concept significantly reduces investment costs as well as plant size, and is nearly maintenance-free. Furthermore, the TWIST® plant concept is characterized by its higher process speed and flexibility when structuring welding contours, as compared to conventional joining methods. Hence, it is particularly suitable for small and medium series, which require quick retooling. By using new wave lengths in combination with the TWIST® concept, operators are now able to weld transparent components together without an infrared absorber and at high speeds.
To bond metal with commercially available plastics, the Fraunhofer ILT has developed a laser-supported joining process that can dispense with using additional material. A suitable structuring of the metal's surface at high speed allows form fit joints to be attained above the bonds with high strength.
