Custom Torsion Spring

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

If you want custom torsion springs or custom tension springs, 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.

Torsion Spring Supplier & Manufacturer

KENENG is a torsion spring manufacturer with modern forming machinery and production technology. Since the establishment of the company, KENENG has been committed to helping customers obtain springs suitable for their applications. Springs manufactured by KENENG come in many forms and can be used in a variety of ways. At the same time, KENENG is a double torsion spring manufacturer that can custom double torsion springs.

What are double torsion springs?

The design principle of torsion springs is relatively complicated, which can be divided into single torsion springs and double torsion springs.

Double torsion springs are two springs with the same number of turns obtained by winding a spring material on the same mandrel in opposite directions. Whether it is double torsion springs or single torsion springs, you can find them all in KENENG’s product list.

Advantages of KENENG:

  • An infinite variety of torsion spring end shapes can be produced.
  • Through the use of new manufacturing techniques, the torsional end position can be held within surprisingly tight tolerances.
  • If the specification calls for very long spring legs, we recommend that you discuss your requirements with a KENENG engineer.
  • Our employees have excellent manufacturing capabilities and will strive to keep your production costs as low as possible.
  • KENENG can produce all kinds of precision custom springs.
  • We can produce high-tech springs for low-tech companies, low-tech springs for high-tech companies.

FAQ of Torsion Springs

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.
