Aluminum alloy high-performance automotive lightweight research and development has made significant progress

 Suzhou Jincheng Precision Die Casting Company (hereinafter referred to as "Jin Cheng Precision") and Soochow University jointly established postdoctoral innovation practice base, in the field of high-performance automotive lightweight casting aluminum alloy research and development has made breakthroughs in the field of research and development, for the new energy automotive lightweight technology development to inject a strong impetus.

 Overcoming the core problems of lightweighting

 Focusing on "the development of high-performance automotive lightweight casting aluminum alloy and microstructure control", Dr. Yu Jia Min was introduced to form the R&D team. Through the optimization of material composition, heat treatment process innovation and microstructure control technology, we developed a new type of aluminum-silicon alloy materials, whose yield strength, tensile strength and elongation reached the industry-leading level, and whose thermal conductivity was significantly better than that of similar products, which meets the urgent needs of new energy automobiles for high-strength and high-conductivity materials.

 Effective market application

 The developed high-performance aluminum alloy thin-walled parts have been widely used in new energy vehicles, such as three-in-one motor shell, controller box and other key components, the product qualification rate of over 99%, for two consecutive years to occupy more than 35% of the domestic market share in the segment, ranking first in the country. In addition, the lightweight materials developed by the company have helped customers realize a weight reduction of more than 30% in components and enhance the range of new energy vehicles.

 Empowering Continuous Innovation

 At present, the company's R & D team size of more than 150 people, covering die-casting experts, mold engineers and university researchers, and with Northeastern University and other 11 institutions to carry out in-depth cooperation. Through the "research for production" model, the company has incubated three leading international technologies and formed stable cooperation with leading enterprises such as Sunny Power and Weifu Hi-Tech.

 Anchoring global competitiveness

 In the future, we will further deepen the research on material genome engineering, lay out the cutting-edge fields of ultra-thin-walled and ultra-high-strength aluminum alloys, and at the same time promote the intelligent production line to upgrade to Industry 4.0, so as to achieve the global market share of automotive lightweight parts to 15% by 2026. With the collaborative innovation mode of "technology + talent + industry", the company has become a leader in the field of aluminum alloy lightweighting, providing a benchmark for the independent control and high-quality development of new energy automobile industry chain. This achievement is a vivid practice of the deep integration of industry, academia and research, and a milestone in building a global high-end manufacturing hub.
