Custom Flat Wire Spiral Torsion Springs for Industrial Machinery

s a professional custom spring manufacturer located in Dongguan, we specialize in precision flat wire spiral torsion springs for global industrial customers. This multi-coil spiral torsion spring is wound with flat rectangular spring steel, capable of outputting stable high torque during rotational deflection. All flat wire torsion springs can be customized strictly according to customers’ 2D drawings, 3D models and physical samples. With compact structure and strong torsional force, these spiral torsion springs are widely adopted in automation equipment, mechanical hinges, clutch assemblies, tool hardware, household appliances and other mechanical structures that require rotary resetting and torque transmission. We provide full OEM & ODM customization services to meet diverse structural and load requirements of worldwide industrial buyers.

CNC Precision Manufacturing Technology for Flat Wire Spiral Torsion Springs

Custom flat wire spiral torsion springs are manufactured using dedicated CNC flat wire coiling equipment. The machine precisely controls flat wire width and thickness, inner diameter, number of coils, torsion angle, as well as the shape and length of torsion arms to guarantee outstanding consistency during mass production. After coiling and forming, springs undergo high-temperature stress relief and quenching & tempering heat treatment to stabilize elasticity and effectively prevent fatigue deformation under long-term cyclic torsion. Subsequent deburring removes sharp edges to avoid assembly scratches.
Our mature production line can handle flat wire torsion springs, round wire torsion springs, compression springs, extension springs and various special-shaped wire forming hardware simultaneously to support one-stop hardware procurement.

Product Features & Industrial Advantages of Flat Wire Spiral Torsion Springs

Flat wire spiral torsion springs adopt flat rectangular wire spiral winding structure to provide powerful torsion force within limited installation space. Their core advantages for industrial applications are summarized below:
Flat wire spiral structure: Higher torque output than ordinary round wire torsion springs under the same outer diameter, saving installation space effectively;
Stable elastic performance: Complete heat treatment process ensures good fatigue resistance, not easy to lose elasticity under repeated rotation;
Highly flexible torsion arm design: The bending direction, arm length and arm angle can be customized freely to match your assembly structure;
Multiple material selections: Carbon spring steel for general load scenarios and stainless steel for anti-corrosion working environments;
Customizable surface treatments: Black oxide, plating and shot blasting options to improve rust resistance and surface texture.
Unstable torque, inconsistent coil diameter or easily deformed torsion arms will cause failure of mechanical reset. High-precision custom flat wire spiral torsion springs are critical to guarantee long-term stable operation of your machinery and equipment.
