LISI GROUP - Integrated report 2022

PARKING BRAKES: COST OPTIMIZATION  AUTOMOTIVE #PROCESS LISI AUTOMOTIVE has optimized the manufacture of its parking brake components (EPB). The removal of the EPB screw grinding step has made it possible to optimize the cost of the solution while maintaining the same level of quality. AN EXPERTISE CENTER FOR MULTI‑MATERIAL ASSEMBLIES  AUTOMOTIVE #R&D Bolstered by the success encountered during the various visits and demonstrations carried out in 2022, the industrial demonstrator set up at the end of 2021 on the Delle site (in the Bourgogne-Franche-Comté region) to support the development of the LISI μ MACH ASSEMBLY PROCESS ® (see opposite) becomes a center of expertise dedicated to multi-material assembly solutions. The whole range of assembly solutions for vehicle lightening will be presented there. LISI µ MACH ASSEMBLY PROCESS ® , BREAKTHROUGH INNOVATION  AUTOMOTIVE #INNOVATION Presented in 2021, the LISI μ MACH ASSEMBLY PROCESS ® technology developed by LISI AUTOMOTIVE is arousing strong interest in the industrial and academic world. This mechanical assembly process by laser micro-machining of surfaces and in situ additive manufacturing makes it possible to produce numerous mechanical and electrical assembly configurations, with no geometry limit. The manufacture of assembly points based on aluminum alloy (AlSi10Mg) makes it possible to combine low added mass with optimized mechanical resistance. Cold, without oxidation or mixing of materials, the LISI μ MACH ASSEMBLY PROCESS ® process also offers extremely low contact resistance and thus optimizes the life of the battery of electric vehicles. PARTNERSHIP WITH FORVIA ON MULTI- MATERIAL ASSEMBLIES  AUTOMOTIVE #PROCESS Responses to the challenges of lightening involve in particular the combination of materials of different natures and densities, such as metals, composites or thermoplastics. In order to increase the bond strength of these assemblies, LISI AUTOMOTIVE is co-developing with the equipment manufacturer FORVIA the use of laser micro-texturing of the metal inserts used as reinforcement. In this method, the mechanical anchoring of the inserts is optimized when they are inserted by overmoulding in a composite material. The breaking load can then be multiplied by 20 compared to the same assembly without micro-texturing. EMBEDDED MECHATRONICS: PROCESS OPTIMIZATION  AUTOMOTIVE #PROCESS LISI AUTOMOTIVE has succeeded in optimizing the production of drive screws used to set the internal parts of a vehicle in motion (seats, headrests, etc.). Thanks to the laser cutting of the screw heads, the design can be immediately adapted to the customer’s request without modification and without creating specific tools. NEW FASTENER LAYING SOLUTIONS  AUTOMOTIVE #PROCESS LISI AUTOMOTIVE’s French, German and American design offices have succeeded in optimizing the attachment of the fasteners to the interior and exterior trim components of the vehicles. This solution saves time on customer production lines and facilitates the automatic installation of clips. CARRYING THE STRATEGIC VISION BEYOND INNOVATION 47 LISI – 2022 INTEGRATED REPORT
