42 — LISI – 2021 INTEGRATED REPORT #1 Innovation AUTOMOTIVE OPTIMIZATION AND WEIGHT REDUCTION OF ASSEMBLIES Screws for battery packs LISI AUTOMOTIVE’s teams have developed a new screw whose head sealing system ensures the assembly and sealing of the battery pack of electric vehicles. This new solution, used to fasten the cover of the battery pack in the vehicle, benefits from the strong development of the market for hybrid and electric vehicles. AEROSPACE PRODUCT INNOVATION / RANGE EXTENSION Locking solutions for critical junctions LISI AEROSPACE now offers a complete range of locking solutions dedicated to critical junctions such as helicopter rotor mountings, wheel and brake assemblies or reactor pylons. This new mechanism adds up to the conventional braking systems in order to prevent any loosening, even in case of strong vibrations. It has been optimized to benefit from a compact and light design, a very high level of resistance and to allow quick, ergonomic installation. AUTOMOTIVE PRODUCT INNOVATION / RANGE EXTENSION A range for vehicle lightweighting LISI AUTOMOTIVE continues to expand its range of assembly solutions designed to reduce the weight of vehicles. The new generations of special nuts and spacers designed in 2021 have been developed in plastic or metal-plastic. Weight gain, combined with slashed costs, reaches 30 to 50% compared to the previous metal versions. AEROSPACE OPTIMIZATION AND WEIGHT REDUCTION OF ASSEMBLIES Automating pre-assemblies The new CLY-336CC Flush staple is a flush robotic temporary fastener. This automatable solution for pre-assembling structural elements (wings and fuselage sections) is temporarily installed in the final holes to facilitate the tightening of the elements to be assembled. Its installation can be automated, operated by a robot, or carried out manually using portable power tools. By avoiding any protrusion on the external surface of the structure during the assembly phase, this innovation eliminates the areas to be bypassed by the robot and makes it possible to optimize the assembly phases.
