Torsion Springs

Custom Torsion Spring Supplier and Manufacturer

Torsion springs are a type of flat spiral coil or helical-shaped springs used in applying torque or storing rotational energy. Unlike other springs such as compression or extension springs that require a linear force to push or pull, torsion springs store and release rotational energy via torque as a measure of force. Torque causes the spring to rotate on its axis while resisting or applying a load. So we think of torque as the rotational equivalent of the linear force driving the compression and extension springs.

This type of spring is normally a close wound but can have a pitch to reduce friction between the coils. They provide resistance to forces applied by rotation or twisting. Torsion springs can be designed to work in a counter-clockwise or clockwise rotation, thus determining the direction of the wind depending on the application.

We are a professional torsion spring manufacturer. KENENG has 110+ Technical workers, 11 QC persons, 4 engineers, 3 packaging lines, 3 sales terms, various specifications of fully automatic computer spring coiling machine, computer spring grinding machine, continuous mesh belt quenching furnace, tempering furnace, spring tension and compression testing machine, spring fatigue testing machine, and a complete set of spring hot coil equipment. We support customizing all kinds of springs like Disc springs, annular springs, leaf springs, coil springs, truncated cone scroll springs, torsion bar springs, etc.

KENENG will provide custom torsion spring services from design to prototype to production.

If you want custom spring torsion, these instructions are available:

1. Provide the necessary parameter information for the spring.

Wire diameter (spring wire diameter), outer diameter (spring outer circle diameter), inner diameter, length (total length of spring including hook), number of turns (effective number of turns),  unfolded length (unfolded length of spring material), the angle (the original angle between the two twist angles).

2. Provide other requirements.

  • Spring rotation direction (left-hand, right-hand), material (stainless alloys, beryllium copper, brass, Hastelloy, Inconel, Monel, titanium, spring steel, carbon steel, etc.),
  • Surface treatment (black oxide, plating (Zinc, Nickel, Tin, Gold, Silver ), phosphating, powder painting, color coding, shot peening, sandblast, etc.),
  • Technical requirements for strength requirements(Elastic),
  • Hook shape (round hook, semi-circle hook, U-shaped hook, middle ear, side hook, etc.),
  • End shape.

Torsional springs are usually close-fitting, but the springs are spaced to reduce friction. They exert resistance to rotation or rotational forces. According to the application requirements, the design of torsion spring rotation (clockwise or counterclockwise), so as to determine the spring rotation.

  1. The thickness of the spring wire should be selected according to the size of the necessary spring force. Usually represented by the letter d.
  2. It is also necessary to understand the cross-sectional diameter of the torsion spring.
  3. The natural length of the torsion spring and the maximum torsion angle of the torsion spring. Only by calculating the maximum force that the torsion spring can support can the service life of the torsion spring be extended.
  4. It is also necessary to understand the maximum load of different torsion springs, and then you can choose the spring according to your own needs.
  5. Special attention should be paid to the spiral direction of the spring, which is the most common mistake area in our daily life. People often misremember the direction of rotation. So this must be kept in mind.
