Why Our Coil Springs Have Minimum Elastic Attenuation
Elastic attenuation is the core failure cause of coil springs in long-term operation. Frequent compression, tension, torsion and complex temperature changes will lead to gradual fatigue deformation, reduced elasticity, unstable mechanical performance, and even equipment failure. As a professional coil spring source factory for global export, we take elastic attenuation and fatigue performance testing as the core quality standard, implementing full-process standardized testing to ensure every batch of springs maintains stable elasticity and long service life in high-frequency and harsh working conditions.
Professional In-House Attenuation & Fatigue Testing System
Different from ordinary manufacturers that only test size and hardness, we focus on dynamic elastic performance detection. Equipped with high-precision spring fatigue testing machines, constant temperature and humidity test chambers, and full-range force testing equipment, we can simulate real working scenarios of springs including high-frequency repeated loading and unloading, alternating temperature environments, and long-duration stress bearing.
We conduct standardized cycle fatigue tests for all coil spring products (compression, tension, torsion and special-shaped springs). Through millions of repeated compression and torsion simulations, we record real-time elastic force change curves, accurately verify elastic attenuation data, and eliminate unqualified products with excessive elasticity loss. Our testing standard ensures that the elastic force fluctuation of finished products is controlled within ±2% after long-term operation, far exceeding the ordinary industry level.
Root Control: Reduce Attenuation From Materials & Craftsmanship
Elastic attenuation is not only guaranteed by testing, but fundamentally optimized by production technology. We strictly select high-quality spring steel, stainless steel and alloy steel raw materials with uniform texture and strong fatigue resistance to avoid elastic fatigue caused by material impurities.
Adopting precise CNC forming + secondary tempering heat treatment process, we effectively eliminate internal stress generated during spring coiling. Combined with professional shot peening treatment, the surface toughness and fatigue resistance of the spring are greatly improved, which fundamentally delays elastic attenuation, prevents permanent deformation, and ensures the long-term stability of spring elastic performance.
Full-Batch Traceable Quality Inspection Standard
We implement batch sampling and full-item testing mechanism for all export orders. Each batch of springs undergoes elastic attenuation test, load test, fatigue life test and dimension calibration, with complete test reports retained. All test data and production information are traceable, supporting third-party detection and customer verification.
Whether it is standard coil springs or customized non-standard products according to drawings and samples, we uniformly implement strict attenuation testing standards to ensure zero obvious elastic weakening during the service life.
