Beijing, November 27, 2024 – The first domestically developed self-developed CFRT (Continuous Fiber Reinforced Thermoplastic Composite) material jointly developed by Li Auto, Rochling and Freco has successfully rolled off the production line at Rochling’s Kunshan plant, marking that Li Auto has independent formula development and part design capabilities in the field of CFRT materials. In this process, the technical support of Mingke steel belt has played an important role, especially in the research and development and application of continuous isostatic hot and cold pressing alternating continuous die casting technology, which has provided strong support for the successful implementation of Freco’s CFRT material in Li Auto.
The successful development and application of domestic CFRT materials have brought many advantages:
1. Technological independence: The development of domestic CFRT materials has broken the long-term monopoly of foreign suppliers, achieved technological independence, and provided more choices and greater development space for the domestic automotive industry.
2. Performance improvement: Compared with imported materials, domestic CFRT materials are superior in puncture resistance, and the puncture resistance strength has exceeded 1000N/mm for the first time in the industry, which greatly reduces the risk of puncture of the fuel tank and provides users with a safer guarantee.
3. Cost-effective: Localized CFRT materials help to reduce dependence on high-priced foreign materials, reduce costs through localized production, and improve the cost performance of materials.
4. Industry promotion: The successful launch of domestic CFRT materials has played an important role in promoting the localization and application of CFRT materials, and promoted the development and technological progress of domestic related industries.
5. Environmental protection and sustainability: CFRT materials are recyclable and reusable, environmentally friendly, and in line with the trend of sustainable development.
6. Wide application: Due to its high strength and low density, CFRT material has a wide range of application prospects in aerospace, automobile, shipbuilding, rail transit and other fields.
The continuous and automated composite material manufacturing process solution of Mingke steel belt not only improves production efficiency, but also ensures the consistency of product quality. The static isobaric double belt press technology provides a uniform pressure distribution for the forming and curing of the composites, ensuring the compactness and surface quality of the composites. This project marks the successful import substitution of static isobaric continuous press equipment applied to automobile lightweight, and the realization of mass production capacity.
With the successful launch of Li Auto’s self-developed CFRT material, the technical strength of Mingke steel belt has been further verified and demonstrated. In the future, Mingke Steel Belt will continue to deepen its cooperation with automotive lightweight, robot material lightweight and other companies, continue to develop industry-leading material solutions, explore application opportunities in more parts of the body, escort the safety of users, and promote the lightweight and sustainable development of the automotive industry.
