Urgent Lightweighting Demand Accelerates Application of New Materials and Processes
Category: Company News
To increase the range of electric vehicles and reduce energy consumption, automotive lightweighting has become an irreversible technical trend. This places higher demands on parts materials and manufacturing processes, expanding the application of aluminum alloys, high-strength steel, carbon fiber composites, and engineering plastics.
In body structural parts, hot-formed ultra-high-strength steel and aluminum die-casting have become mainstream. Tesla's promoted integrated die-casting technology consolidates dozens of parts into a single large aluminum casting, significantly reducing weight, weld points, and production costs. In interior and exterior trim, modified plastics and long-fiber reinforced thermoplastics are gradually replacing metal materials due to their excellent strength and lightweight properties.
Parts suppliers must keep pace with advancements in materials science and invest in corresponding molds and production equipment. For instance, interior giants like Faurecia are developing bio-based materials using natural fibers to meet environmental requirements while achieving lightweighting. This lightweighting race is not just a competition between materials but a comprehensive contest of design and manufacturing capabilities, driving automotive manufacturing towards greater efficiency and environmental friendliness.
