Blackened Waved Spring - Rust-Resistant for Precision Machinery
Precision machinery demands elastic elements with exceptional rust resistance and dimensional stability. Our blackened waved spring delivers superior performance for such critical applications, featuring a metal ring with precisely engineered peaks and valleys that offer excellent elasticity, impact resistance, and consistent load-deflection characteristics.
Advanced Surface Treatment
The advanced blackening surface treatment—achieved through alkaline oxidation—forms a dense Fe₃O₄ protective layer (5-8μm thickness) that provides outstanding rust resistance. This treatment passes 500+ hours of neutral salt spray testing (per ASTM B117) and effectively prevents corrosion in humid or industrial environments while enhancing surface hardness (HV 450-550) and reducing friction by 28%.
Technical Specifications
Property Specification
Tensile Strength Up to 1,250 MPa
Dynamic Load Capacity Withstands 420G dynamic loads
Diameter Range 8mm - 350mm (standard single-layer closed waved springs)
Dimensional Accuracy ±0.02mm
Temperature Stability Up to 300°C (with 50CrVA material)
Material Options
  • 1074 High-Carbon Steel: Excellent springback for repetitive motion applications
  • 60Si2MnA Alloy Steel: Superior fatigue resistance for 10⁶+ cycles
  • SUS302 Stainless Steel: Enhanced corrosion resistance for cleanroom environments
  • 50CrVA: High temperature stability up to 300°C
Manufacturing Excellence
Our production process integrates computer numerical control (CNC) coiling and laser welding for dimensional accuracy, while FEA simulation (ANSYS) ensures optimal wave geometry for minimal stress concentration. Each spring undergoes rigorous quality validation, including load testing (±3% tolerance), metallographic analysis, and adhesion testing of the blackened coating.
Applications
Ideal for precision gearboxes, robotic arms, medical imaging equipment, and semiconductor manufacturing tools. Our blackened waved springs provide reliable axial preload, reduce component wear, and extend machinery service life.
Custom Solutions Available: SUNZO offers both standard and fully customized solutions with end-to-end technical support, from material selection to prototype development, ensuring seamless integration into your precision machinery systems.
