Torsion springs, also known as radial springs or angle springs, can be used for various applications and can be made from a variety of materials and surface treatments. It is a spiral spring, with one or two spring legs providing radial (rotational) force. They can apply torque or resist externally applied torque. Most torsion springs are usually tightly wound (coil contact) to ensure stability or maximize space efficiency. However, when applications require low friction or do not use gaskets to fill specific areas, torsion springs can be designed with spacing or space between coils. We can produce any type of torsion spring to meet your specifications. They can be used in almost any field, from simple old machines to complex medical equipment and space applications. Regardless of the industry, the demand for customized torsion springs in engineering is always high.

Torque spring configuration
There are multiple options for configuring torsion spring legs, so torsion springs can be connected in different ways. The specifications of torsion spring legs should consider factors such as leg angle, leg length, and leg style. Springs that are straight or parallel on the same side are considered to have a 0 º leg angle, and the increased angle is located in the unfolding direction. Common torsion spring designs include straight torsion springs, straight bias torsion springs, hinge torsion springs, short hook ends, and hook end designs. The end of the torsion spring can be designed with customized bending, twisting, hook end or circular end to meet your project needs. The torsion springs we manufacture offer 90 degree, 120 degree, 180 degree, 210 degree, 270 degree, 300 degree, and 360 degree free leg position and straight leg options. The customized double torsion spring consists of a set of right-handed coiled coils and a set of left-handed coiled coils. These coils are connected, usually with an untwisted section between the windings, working in parallel. These parts are designed separately, and the total torque is the sum of the two.

Requirements for customized torsion spring design
As an experienced manufacturer of torsion springs, we manufacture customized springs in various sizes, materials, and thicknesses to meet any application needs. Miniature torsion springs are used in electronic products, while larger torsion springs can be used for industrial purposes.
When designing torsion springs, spring manufacturers like us need to consider several key factors to ensure their effectiveness and maximize the service life of the spring.
It is necessary to carefully analyze the load requirements and required torque to determine the appropriate spring diameter, wire size, and coil configuration.
The selection of materials is also important, as it affects the flexibility, fatigue strength, and corrosion resistance of the spring.
In addition, factors such as the number of effective coils, helix angle, and wind direction must be considered to achieve the required force application and torque output.
Appropriate end handling and connection methods are also crucial for ensuring optimal performance and lifespan.
By carefully considering these design aspects, spring manufacturers can create torsion springs that provide precise and reliable force, meeting the unique requirements of various applications. Here are some common applications you may have encountered using torsion springs.

material
Twisting springs are made of steel because steel has high stiffness, and the most common materials are hard drawn steel, stainless steel, piano wire, and spring steel. When lightweight springs are needed, certain types of high-strength plastics are used. The main characteristic of a torsion spring is that it is tightly wound, which is necessary to generate torque.

spring steel
Spring steel is a group of industrial grade materials known for its high elasticity, flexibility, and strength. It can be compressed, bent, stretched, and twisted to its elastic limit, and then restored to its original shape without deformation. These springs also have high fatigue strength and durability, and are inexpensive. Spring steel contains high carbon concentration. The types of spring steel are:

Music Line
hard-drawn wire
Oil tempered steel wire
Cold rolled flat spring steel
stainless steel
What are the commonly used grades of stainless steel in the production of torsion springs, and what are their mechanical properties and corrosion resistance?

302 level
Grade 304
Grade 316
17th to 7th grade PH
alloy spring steel
What alloy spring steels are commonly used for torsion springs, and how do elements such as vanadium, manganese, silicon, chromium, nickel, and molybdenum enhance their applicability in high impact and impact applications?

chrome vanadium
Chromium silicon
Silicon manganese
copper-base alloy
Copper based alloys have excellent electrical properties, corrosion resistance, and sub zero temperature performance. They are known for their high strength and ductility, but they are often more expensive than spring steel and stainless steel. Common copper based alloys used in torsion springs include:

Phosphor bronze
spring brass
Beryllium Copper
Monel 400
Monel K 500
waspaloy
Nickel based alloys have excellent corrosion resistance and perform well at both high and below zero temperatures, making them highly suitable for harsh environments. However, their resistance is high, making them unsuitable for electrical applications. The commonly used nickel based alloys in torsion springs include:

No. 286
Inconel 600
Inconel 718
Inconel X-750
Hastelloy alloy
Torque springs can be made of circular, square, and rectangular wires. Circular wires are the most common and easily obtainable. For square and rectangular wires, sharp corners should be avoided to prevent stress concentration; Round the corners to alleviate this problem.
