Metal Forming Intelligent Manufacturing: Fifteen Years of Partnership: The Journey of Deep Collaboration Between Anhui Zhongding and SEYI Technology
Anhui Zhongding Group is a rapidly growing large-scale automotive parts supplier in China. With a revenue of 17.25 billion RMB in 2023, it ranks among the top 100 global automotive parts suppliers. The company supplies parts to leading automotive manufacturers such as Volkswagen, General Motors, Ford, BMW, Daimler, Changan Automobile, BYD, Volvo, Renault-Nissan, and PSA Peugeot-Citro?n. Anhui Zhongding Precision Technology Co., Ltd., a subsidiary of Zhongding Group, is a large professional stamping company. Since 2010, it has been in strong collaboration with SEYI Mechanical Industrial Co., Ltd. By the end of 2024, Anhui Zhongding has purchased 139 sets of SEYI stamping machines, building a strong stamping production capability, becoming a well-known success story in the industry.
In 2024, the MFC "Metal Forming Intelligent Manufacturing" team traveled to Xuancheng, Anhui, to interview Mr. Xiao Zheng, the manager of the equipment department at Zhongding Precision.
● Anhui Zhongding Precision Technology Co., Ltd. is responsible for the stamping business of Zhongding Group.
Established in July 2006, Anhui Zhongding Precision Technology Co., Ltd. is a Sino-Japanese joint venture between Anhui Zhongding Group and Kaito International Co., Ltd. of Japan. With a registered capital of 96 million RMB and approximately 1,000 employees, the company primarily produces various hardware products and metal stamping parts. In addition to providing supporting parts for the enterprises within the Zhongding Group, it also develops business in the automotive OEM and other component markets.
● Anhui Zhongding Precision Technology has purchased as many as 139 stamping machines from SEYI.
In terms of stamping equipment procurement, Anhui Zhongding Precision Technology has purchased a total of 139 high-performance SEYI stamping machines. These include a wide range of models, from 160-ton to 200-ton SN1 series C frame crank presses and solid Frame crank presses, to 300-500-ton SLS series closed crank link presses, as well as large 600-1200-ton SLG series straight side crank Link-Motion presses. These machines have built multiple stamping production lines, ranging from small to large parts, injecting strong power into production.
It is worth mentioning that among these, Zhongding Precision’s heavy-duty SEYI stamping machines total 15 units, which operate under high loads year-round, steadily supporting heavy stamping tasks.
In addition, Anhui Zhongding Precision has also made significant investments in automation. The company has introduced 63 advanced pieces of equipment, gradually expanding from five-pair, six-pair machines to seven-pair, eight-pair, and nine-pair machines. Coupled with cutting-edge technologies such as visual feeding, robotic arms, automation feeding lines, and visual feeding lines, this has enabled a smart leap in the production process. The automation has reduced the need for manual labor, ensured high consistency of stamped parts, and greatly improved efficiency and precision.
● SEYI SLG Series Mechanical Press: The Preferred Equipment for Large Stamping Parts Forming
The SEYI SLG series machines are ideal for forming medium to large automotive sheet metal parts. They utilize a crankshaft link drive gear mechanism, providing flexible contact during stamping, significantly reducing vibration, noise, and high temperatures, thereby extending die life. The energy-efficient design effectively saves over 20% in energy consumption.
Key features include:
- Designed with tie-rod structure on the frame and adopting gear driving component with four connecting rods, the rigidity of main body increases extensively.
- Large-tonnage air-cushion die pad combined with locking and adjustment mechanisms, accommodating various stroke and movement requirements.
- High-torque wet clutch/brake for improved clutch lifespan and environmental protection.
- High-response hydraulic overload protection device effectively resolves die jams and prevents overload usage.
- Human-machine interface for precise control over stroke and die pad pressure.
-
PLC monitoring system that allows real-time tracking of machine operation status.
● Why did Anhui Zhongding Precision choose SEYI Presses among all competitors?
Xiao Zheng said: "There were numerous considerations behind this decision. During the initial equipment research phase, our team conducted a detailed comparison of both domestic leading brands and imported presses. Ultimately, SEYI was selected, with the key factor being its exceptional performance parameters. Whether it is the precise control of stamping force or the stability of its operation, SEYI stands out. Furthermore, its production structure is designed logically, aligning perfectly with Anhui Zhongding Precision's diverse production needs. The most important factor, however, is safety. SEYI presses are equipped with safety light curtains, acting as loyal guardians, constantly protecting the safety of operators and ensuring worry-free production."
Over the past fifteen years, SEYI Technology has provided Anhui Zhongding Precision with more than just high-quality equipment. In terms of technology and automation parameters, SEYI has offered substantial support, helping Anhui Zhongding Precision overcome technical bottlenecks and optimize production processes time and time again.

Additionally, SEYI Technology's after-sales service is an indispensable highlight of this successful partnership. Whether it is mechanical repairs, electrical maintenance, or automation issue handling, SEYI is always quick to respond within 24 hours, ensuring smooth production operations with professional and efficient service.
As major automotive parts companies increasingly embrace digitalization and informatization, SEYI’s automated stamping production lines combine advanced presses, automation equipment, computer control systems, and data analysis tools, achieving a high level of automation and intelligence in the production process. Moreover, it seamlessly integrates production data into the company’s production management system.
● Looking Ahead: ESG and Digitalization as Key Focus Areas for Future Stamping Production Lines
Looking to the future, the production lines jointly built by Zhongding Precision and SEYI will place a strong emphasis on environmental protection and energy conservation. On one hand, low-energy-consuming equipment will be selected to reduce energy consumption from the source. On the other hand, efforts will focus on minimizing waste generation and pollutant emissions, ensuring that the entire production line aligns with the ISO 14001 environmental management system standards. In the dimension of digital management, future production lines will need to deeply integrate with advanced production management systems to capture and precisely analyze production data in real-time. This will help optimize production plans and refine inventory management, thereby enhancing the company's response speed and adaptability to market changes.
As an industry leader, Anhui Zhongding Precision has made a strategic choice in selecting SEYI Technology. Through their joint efforts, they are writing their own industrial legend.
Looking ahead, there is every reason to believe that both parties will continue to forge ahead, creating even greater achievements!
