On September 23, Jinan No. 2 Machine Tool Group successfully delivered the ZSK-2.5×1850 unwinding and blanking line to Great Wall Motor Company following user pre-acceptance. This marked a significant milestone as it is China’s first high-grade unwinding and blanking line with complete independent intellectual property rights, breaking the long-standing reliance on imported technology in this critical area.
The product is an advanced automated sheet processing system designed for unwinding, cleaning, leveling, blanking, and palletizing of automotive outer cover coil materials. It is versatile and can be applied across various industries such as automobiles, light manufacturing, and national defense. With the automotive industry in China undergoing continuous upgrades, there's a growing demand for high-end production solutions that meet stricter quality and efficiency standards. As a result, the need for advanced unwinding and blanking systems has surged, yet most domestic automakers have traditionally relied on foreign imports for such equipment.
Jinan No. 2 Machine Tool Group has expanded its product portfolio beyond forging equipment and CNC machine tools, entering the automation sector. Since the 1990s, through strategic collaborations and technology integration with global leaders, the company has achieved rapid and high-level development. It now offers a wide range of automation solutions, including stamping systems, unwinding and leveling lines, and oiling machines, capable of delivering comprehensive high-end automation products both domestically and internationally.
Since 2002, Jinan No. 2 Machine Tool has partnered with foreign companies to supply three high-end unwinding and blanking lines to Chery, Hainan Mazda, and Jianghuai Automobile. In 2023, the company signed its first domestic contract with Great Wall Motor for a high-end unwinding and blanking system, marking a breakthrough in ending foreign dominance in this field. After ten months of intensive development, this highly complex line—featuring the most challenging domestic production technology, the largest number of components, and the highest manufacturing difficulty—was completed in September and passed user pre-acceptance, reaching international standards in performance and quality.
