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. The project focused on addressing critical challenges in the automotive industry, particularly the short service life and high maintenance costs of stamping dies. By leveraging the interaction between lasers and materials, combined with intelligent measurement technologies, the team developed an advanced surface enhancement process that significantly extended the lifespan of large-scale automotive stamping dies. This groundbreaking technology has already been transferred to Shanghai Volkswagen Automotive Co., Ltd., promising substantial economic benefits for the company. On May 18th, a panel of experts—including Academician Xu Zuyan, Academician Guan Bridge, and Academician Zhou Shouyi—alongside representatives from Shanghai Volkswagen, visited the Institute of Mechanics to review the project’s progress. They were given a live demonstration of the laser hardening process and were impressed by the system's capabilities. Experts unanimously agreed that the project's outcomes have reached international standards. They emphasized the importance of further advancing the technology in areas such as laser surface hardening for automobile molds and encouraged rapid deployment across the industry to address long-standing issues with die longevity. The goal is to achieve industrialization and support the broader development of China’s automotive manufacturing sector. The project resulted in the development of a comprehensive "Integrated Laser Intelligent Manufacturing and Flexible Processing System." This system integrates high-power industrial solid-state lasers, 5-axis robotic arms, intelligent surface measurement, simulation software, and advanced beam control technologies. It also includes a robust database and mathematical models tailored for automotive mold applications. The system enables 3D laser processing, rapid prototyping, and intelligent, flexible, and modular manufacturing processes, supporting digitalization and integrated control. Throughout the project, the Chinese Academy of Sciences leveraged its multidisciplinary strengths and collaborated with various domestic and international institutions, including Sweden’s Luleå University of Technology, the Shenyang Institute of Automation, and several open labs. Close collaboration with Shanghai Volkswagen ensured that the project met real-world engineering demands and aligned with user expectations. As a national research institution, the Institute of Mechanics continues to focus on cutting-edge scientific and technological advancements, conducting forward-looking research in advanced manufacturing and related mechanics. Its work lays the foundation for future innovations in laser-based intelligent manufacturing and contributes to the growth of China’s manufacturing industry. Source: Xinhua News Agency
