LISI AUTOMOTIVE EBS fluo-tapping screw Guided by market demand in terms of lighter vehicles, LISI AUTOMOTIVE has chosen to direct its R&D efforts towards solutions that facilitate multi-material assemblies. One outcome of this strategy, the EBS fluo-tapping screw allows materials of different natures to be assembled together where partially overlapping. Thanks to its specific advanced geometry, it can perforate high-strength steels, aluminum alloys or composite materials, while forming a thread by plastic deformation in the two materials to be assembled.  Gains / Benefit – Weight gains by facilitating multi-material assemblies. LISI AUTOMOTIVE µ-MACH‑AP ® : a 3D process for multi‑material assemblies To facilitate assembly between several materials, LISI AUTOMOTIVE has developed, in collaboration with the Bourgogne Carnot Institute of the University of Technology Belfort-Montbéliard, an in-situ innovative additive manufacturing process, which combines laser texturing and supersonic cold projection of metallic powder. This technology, called µ-MACH-AP ® , allows for robust assembly between two parts placed end-to-end, or partially overlapping. It is an innovative alternative for making multi-material assemblies, without limitation of geometry. Gains / Benefit – Weight gain, no limitation in geometry of multi-material assemblies, agile process. Innovations / Products & Processes 42 LISI 2019
