Raw Material Selection: Stainless steel springs typically use materials such as 304, 316, and 631 stainless steel, which possess good corrosion resistance and strength.
Wire Processing: Stainless steel wire is cold-drawn to obtain the required diameter and hardness, ensuring the dimensional accuracy and surface finish of the spring.
Spring Forming: Using specialized spring forming machines, the wire is bent, twisted, or compressed into the desired spring shape using mechanical or thermal force.
Heat Treatment: Heat treatment processes include tempering, quenching, and solution treatment to improve the spring's strength and corrosion resistance.
Surface Treatment: Surface treatments include polishing, pickling, and electroplating to improve the spring's appearance and corrosion resistance.
Precision Adjustment: By adjusting the winding and heat treatment process parameters, the spring's diameter, length, and elasticity are precisely adjusted to meet customer requirements.
Quality Inspection: The manufactured springs undergo quality inspection, including checks on their appearance, dimensions, and elasticity. After passing inspection, they are packaged for transportation and use.
Special Treatment: Stainless steel springs operating in special environments may require additional treatments, such as high-pressure or polishing, to improve their load-bearing capacity and surface finish.
Rust Prevention: Stainless steel springs are prone to corrosion during storage or use due to their susceptibility to reactions with the surrounding environment. Manufacturers apply a metallic coating, such as zinc plating, or perform oxidation or phosphating processes to the spring surface during manufacturing to form a protective film and enhance its corrosion resistance.
