Crack the technical problem of automotive stamping die
The first group of the Chinese Academy of Sciences’ Knowledge Innovation Project, titled “Integrated Laser Intelligent Manufacturing and Flexible Processing Research,†was led by the Institute of Mechanics, Chinese Academy of Sciences. This project focused on addressing critical challenges in the automotive industry, particularly the limited service life and high maintenance costs of stamping dies. By leveraging the interaction between lasers and materials, combined with intelligent measurement technologies, the project significantly enhanced the surface properties of large-scale automotive stamping dies. The developed system has already been introduced to Shanghai Volkswagen Automotive Co., Ltd., offering substantial economic benefits and marking a significant step forward in industrial application.
On May 18th, an expert panel, including Academician Xu Zuyan, Academician Guan Bridge, and Academician Zhou Shouyi, along with representatives from Shanghai Volkswagen, reviewed the project’s progress at the Institute of Mechanics. They witnessed a live demonstration of the laser hardening process and were impressed by the system's capabilities. Experts unanimously agreed that the project's achievements have reached international advanced standards. They emphasized the potential for further breakthroughs in laser surface hardening for automotive molds and recommended accelerating the technology's adoption across the industry to address long-standing issues related to die lifespan.
The system developed under the project integrates several cutting-edge technologies, including a high-power solid-state laser, a 5-axis robotic arm, rapid mold surface measurement, simulation software, and advanced laser beam transmission techniques. It also includes a comprehensive control system and a CAx process database. This integration enables 3D laser processing, rapid prototyping, and intelligent, flexible, and modular manufacturing. The project bridges fundamental research with practical development, advancing both laser processing robotics and laser manufacturing mechanics.
Throughout the project, the Chinese Academy of Sciences leveraged its multidisciplinary strengths and collaborated extensively with domestic and international partners, such as Sweden’s Luleå University of Technology, the Shenyang Institute of Automation, and the LNM and LHD Open Labs. These collaborations helped tackle complex technical challenges and ensured alignment with real-world engineering needs. Close cooperation with Shanghai Volkswagen was essential in ensuring that the final product met user expectations at every stage.
As a national research institution, the Institute of Mechanics continues to focus on the forefront of scientific and technological advancements. It conducts forward-looking, basic, and strategic research in advanced manufacturing and related mechanics, aiming to discover new mechanical phenomena and develop innovative technologies crucial to national development. This project lays a solid foundation for future research in laser intelligent manufacturing and provides a vital platform for the next leap in China’s manufacturing industry.
