Torsion Springs

Torsion Spring Manufacturing

The Active Spring Co is one of the UK’s leading Torsion spring manufacturers and suppliers having the latest and most sophisticated torsion spring coiling machines available today.

We manufacture and supply Single Torsion, Double Torsion and Triple Torsion springs in a wide range of wire diameters and material specifications.

Torsion springs are manufactured from round, square or sectional material with pitched or closed coils with a vast range of leg configurations and dimensions. We manufacture torsion springs using a variety of materials such as carbon steel, stainless steel and Nickel based exotic materials such as Inconel, Monel, Hastelloy and Nimonic.

We supply and manufacture Torsion springs in quantities from one-off to millions, in material diameters from 0.3mm to 30mm. We make torsion springs so small you could fit thousands in the palm of your hand and so large that to lift one spring requires five people.

Wafios are widely regarded as producing the best torsion springs and wire forming machines in the world and we pride ourselves in having the widest range of Wafios machinery and the greatest amount of experience in their use of any spring company in the United Kingdom.

The technical definition of a torsion spring:

Torsion springs differ from both compression and extension springs in both applications of load and method of operation. They are coil springs that exert a torque (or resist a torque) in an arc with the legs rotating around the axis and the body coils being stressed in bending. An infinite number of variations of torsion springs are possible for leg formation but simplicity is often the best guide.

Torsion springs can be manufactured from any of the same materials as compression or extension springs but the most common are drawn carbon steel or stainless steel. Torsion springs should always be used in the “wind up” direction as used in the opposite direction is more likely to cause premature failure of the spring.

Wire Form

Almost the only limit when it comes to wire form manufacture is the imagination of the designer. Almost any conceivable 2D or 3D shape can be achieved although our early involvement in the design process can help to avoid the inclusion of potential failure points. Wire forms can be manufactured using materials from drawn carbon steel and stainless steel to exotic materials such as Inconel X750, 625, 718, Nimonic 90 and Titanium.

Tension

Tension (or extension) springs work in the exact opposite manner to compression springs. They are close–coiled springs that extend under the application of a pulling force applied to a hook or loop at each end of the spring. These can be formed either from the first and last coils of the spring body or by the inclusion of a separate hook, necessitating that the ends of the spring body are “coned” down in diameter or by a screw insert.

Compression

Compression springs are open wound springs that exert a force when compressed with the coils being stressed in torsion. They are generally cylindrical but may be conical, barrel-shaped or concave. They are the most common form of spring used in engineering, accounting for over 50% of all springs manufactured. The ends of a compression spring may be finished in several ways, left open, open and ground, closed or closed and ground. The two most common types of end are closed and closed and ground. The grinding allows the spring to stand upright but may be unnecessary for springs of a small diameter or a large index.

Pressings

Pressings are springs that are manufactured from sheets or strips. They may be flat, have bends, radii, have holes or cut out shapes or a combination of all of the above and can be made from a wide range of materials and are often made from pre-hardened material although sometimes it is necessary to manufacture from annealed material and apply a post-forming harden and temper operation. Most pressings are loaded in bending with the cantilever spring being the most simple.

About Torsion Spring Manufacturing

 

Torsion springs are a critical component in various industrial and mechanical applications, and they play a vital role in ensuring smooth and reliable operations. 

Torsion springs are designed to store and release rotational energy when subjected to torque or rotational force. They are commonly found in everything from door hinges to automotive suspension systems. These springs work by twisting or coiling in response to the applied force, and when the force is removed, they return to their original position, providing the necessary counterforce.

Torsion springs are widely used in the automotive industry, where they help control suspension systems, ensure precise steering, and maintain the integrity of various vehicle components. Furthermore, they are essential in the manufacturing of industrial machinery, ensuring smooth and efficient production processes.

Torsion springs come in various shapes and sizes, and at The Active Spring Company, we have the expertise to custom design and manufacture torsion springs that meet the specific needs of our  customers. We consider factors such as wire diameter, coil direction, leg configuration, and the required torque when creating these springs to ensure they perform optimally in their intended applications.

Our dedication to quality and precision manufacturing ensures that torsion springs we produce are reliable, durable, and built to withstand the rigors of everyday use. We take pride in being a trusted spring manufacturer for our audience. Delivering top-notch torsion springs that meet the highest standards of performance and safety.

Torsion springs are crucial components in a wide range of applications, contributing to the functionality and reliability of various products and systems. As expert spring manufacturers, The Active Spring Company is committed to designing and producing high-quality torsion springs tailored to the unique needs of our  customers, helping them achieve optimal performance in their respective industries.

FAQ’s About Torsion Springs

What is a torsion spring, and how does it work?

A torsion spring is a type of coiled spring designed to store and release rotational energy. It works by twisting or coiling when subjected to torque or rotational force and then returning to its original position when the force is removed.

Where are torsion springs commonly used?

Torsion springs are used in a wide range of applications, including garage doors, automotive suspensions, industrial machinery, and even in simple devices like clipboards and clothespins.

How are torsion springs different from other types of springs, such as compression or extension springs?

Torsion springs are designed to withstand twisting or rotational forces, whereas compression springs resist axial forces (pushing or pulling), and extension springs handle tensile forces (stretching).

What factors should I consider when choosing a torsion spring for my application?

When selecting a torsion spring, factors to consider include the required torque, the direction of coil winding, the material of the spring, wire diameter, and leg configuration. It’s essential to match the spring’s specifications to the specific needs of your application.

Can torsion springs be customised to meet specific requirements?

Yes, torsion springs can be custom-designed to suit your particular application. A reliable spring manufacturer can help create springs that meet your specific size, material, and performance requirements.

What materials are commonly used to make torsion springs?

Torsion springs are often made from materials like high-carbon steel, stainless steel, or various alloys, depending on the application’s requirements and environmental factors.

How do I determine the lifespan of a torsion spring?

The lifespan of a torsion spring depends on factors such as the material used, the application’s frequency of use, and maintenance. Regular inspection and replacement when necessary are key to ensuring the longevity of the spring.

Are there safety precautions to consider when working with torsion springs?

Yes, torsion springs store significant energy and can be dangerous when mishandled. It’s important to follow safety guidelines and consider professional assistance when installing or replacing torsion springs.

Can torsion springs be repaired, or do they need to be replaced if they fail?

Torsion springs are often replaced rather than repaired when they fail, as attempting to repair them can be challenging and potentially unsafe. A qualified technician or spring manufacturer can help with replacement.

Where can I find a reputable torsion spring manufacturer in the UK?

In the UK, you can find reputable torsion spring manufacturers like The Active Spring Company, who can custom design and manufacture torsion springs to meet your specific needs and quality standards.
