Product Description
Detailed Specifications & Features
As a leading manufacturer of high-performance elastic components in China, Jiangsu Sunzo Elastic Technology Co., Ltd. (SUNZO) specializes in the R&D, production, and sales of precision engineered compression springs—helical coil springs meticulously crafted to deliver exceptional performance in automotive and mechanical systems. Backed by strong technical strength, a complete industrial chain, and strict quality control, Sanzhong’s compression springs have become the preferred choice for global high-end customers in automotive, machinery, and other key industries.
Sunzo’s compression springs are defined by precision engineering, where every detail from material selection to manufacturing processes is optimized to meet the rigorous demands of automotive and mechanical applications. As a mixed-ownership enterprise participated by China National Nuclear Corporation (CNNC), Sanzhong has established a research and development center in Nanjing and a production base in Sihong, Jiangsu, covering an area of 60 mu with independently developed production lines and a modern testing center. The company adheres to the concept of "precision manufacturing, performance-driven" and integrates advanced technology into every link of compression spring production.
In terms of material selection, Sanzhong strictly selects high-quality raw materials that meet international standards, ensuring the compression springs possess excellent fatigue resistance, corrosion resistance, and load-bearing capacity. The manufacturing process of precision coil springs undergoes professional procedures including wire drawing, precision coiling, heat treatment, end grinding, shot peening, and phosphating. Equipped with more than 200 sets of advanced equipment such as CNC machine tools, heat treatment furnaces, and automatic pressure sorting equipment, Sanzhong realizes intelligent and automated production control, which not only improves production efficiency but also ensures the consistency and precision of each compression spring’s dimensions, stiffness, and load performance.
Designed specifically for performance in automotive and mechanical systems, Sanzhong’s compression springs play a crucial role in various core scenarios. In the automotive industry, these precision coil springs are widely used in shock absorption systems, clutch damping mechanisms, electric tailgate systems, fuel injection systems, braking systems (ABS, ESP), transmission control, and belt tensioning systems, effectively absorbing shocks, storing energy, and controlling motion to enhance the stability, safety, and comfort of vehicles. Sanzhong has established long-term cooperative relationships with well-known automotive manufacturers such as Changan Automobile and Seres, providing reliable elastic solutions for their core components.
In mechanical systems, Sunzo’s compression springs are applied in construction machinery, hydraulic valves, heavy machinery, precision instruments, and other equipment, adapting to harsh working environments such as high temperature, high pressure, and frequent vibration. With the characteristics of small deformation, high load-bearing capacity, stable performance, and long service life, these springs ensure the efficient and stable operation of mechanical equipment, reducing maintenance costs and improving operational efficiency. The products have been exported to more than 50 countries and regions around the world, serving well-known enterprises such as Sie-mens, Alstom, and Sany Heavy Industry.
Quality is the cornerstone of Sanzhong’s development. The company has passed a series of international quality management system certifications, including ISO 9001, IATF 16949, ISO 14001, and ISO 45001, and has obtained more than 40 patents, forming a complete quality control system from raw material inspection to finished product testing. Sanzhong’s testing center is equipped with dynamic fatigue testing machines, high-temperature environmental chambers, electronic tension and compression testing machines, and other advanced equipment, conducting strict tests on the load, fatigue life, corrosion resistance, and other performance indicators of compression springs to ensure that each product meets or exceeds international standards.Sunzo has participated in the formulation of international ISO disc spring standards and national standards, demonstrating its leading position in the elastic component industry Sunzo Elastic is committed to providing customers with the best elastic technology solutions, and its precision engineered compression springs are dedicated to enhancing the performance and reliability of automotive and mechanical systems. With strong technical strength, strict quality control, and global service capabilities, Sanzhong is moving forward steadily in the field of precision elastic components, creating greater value for customers around the world.
