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 field.
The product is a state-of-the-art automated sheet processing system designed for unwinding, cleaning, leveling, blanking, and palletizing of automotive outer panel coils. It is versatile and applicable across multiple industries, including automotive, light manufacturing, and national defense. With China’s automotive industry undergoing a major upgrade, there is an increasing demand for advanced production systems that meet higher quality and efficiency standards. As a result, the need for high-end unwinding and blanking lines has surged, yet most domestic automakers have traditionally relied on foreign imports.
Jinan No. 2 Machine Tool Group has expanded its product portfolio beyond forging equipment and CNC machines, developing automation solutions that now include stamping systems, unwinding and leveling lines, and steel plate cleaning and oiling machines. Since the 1990s, through strategic collaborations with international firms, the company has achieved rapid growth and established a strong position in the market.
Since 2002, the group has partnered with foreign companies to supply three high-end unwinding and blanking lines to Chery, Hainan Mazda, and Jianghuai Automobile. In 2023, they signed their first domestic contract for high-end unwinding and blanking systems with Great Wall Motor, effectively challenging the dominance of foreign manufacturers. After ten months of intensive development, this complex line—featuring the most difficult domestic production technology, the highest number of components, and the greatest manufacturing complexity—was completed in September and passed user pre-acceptance. It now meets the global standard of similar international products, marking a major breakthrough for China’s industrial automation sector.
