In the face of huge changes of the automobile industry, the automobile manufacture industry is speeding up its integration with emerging technologies and is being transformed and upgraded in the direction of “four trends”. materials are the foundation of automobile manufacture. Lightweight, as one of the main routes of automotive technology development in the future, has higher requirements on the application of materials. The innovation of material technology keeps driving the lightweight technology to progress constantly. The Greater Bay Area Automotive Materials Conference and Exhibition 2023 will provide a zero-distance interaction platform between suppliers of materials and lightweight fields such as steel and aluminum automotive materials, automotive plastics and composite materials, processing and connecting technologies and the terminal users of engine factories and parts and components manufacturers. Focusing on new technologies, new processes, new equipment and new solutions in the field of materials and guided by the core concepts of greenness, safety and cost, it aims to satisfy the individualized material demands of automobile enterprises and further enhance the lightweight level of automobile making in China.
