Torsion Spring Manufacturers
For over 70 years, we at European Springs & Pressings have established ourselves as one of the most reliable spring manufacturers in the UK. We are vastly experienced in a range of fields and highly regarded as leading torsion spring manufacturers, which we have delved into in more detail here.
What Are Torsion Springs?
Torsion springs are a type of coiled spring that work via a rotational motion known as torsion. They are used when there is a need for rotational movements of components.
The most common design for a torsion spring is the cylindrical wound design, which consists of a coiled metal wire, in a left- or right-hand, clockwise or anti-clockwise direction and usually has legs, to which a force can be applied.
How Do Torsion Springs Work?
Torsion springs are usually mounted upon a Mandrel and the force is applied to the spring axially. The rotational motion allows a flexible object to store mechanical energy. This exerts a force, known as torque, in the opposite direction, proportional to the amount it is rotated. As components rotate around the centre of the spring, it will attempt to push them back to their original position.
A common example of a helical torsion spring is used in a door handle, where once opened, the loaded spring returns the handle to its original position. Another good example of a torsion spring in is the spring in a clothes peg.
Torsion springs can be made single torsion or double torsion, which doubles the output force.
Torsion springs have a linear spring characteristic, i.e. if a spring is turned 10˚ to provide torque of 1 Nmm, the same spring will provide a torque of 2 Nmm at 20˚ rotation.
Torque is equal to force x leg length: M = F x A. The closer to the end of the leg the load is applied, the less counterforce is created.
Our engineers work with you from your initial design to final production to ensure that the torsion springs we produce can withstand the stress of the working conditions and environment they operate in.
European Springs & Pressings have over 70 years of experience creating bespoke torsion springs, so you can rest assured all of our products are made to last and are more than capable of being used in the most high-pressure environments.
Leading Torsion Spring Manufacturers and Torsion Spring Suppliers
There are generally two common types of torsion springs:
- Single coil torsion springs
- Double coil torsion springs, which are two single torsion springs connected
European Springs & Pressings can manufacture and supply both types, so whether you’re looking for a standard torsion spring or a large torsion spring, we can provide you with precisely what you need.
As one of the leading torsion spring manufacturers in the UK, European Springs & Pressings is proud to offer our customers an extensive range of products. Our torsion springs come in all shapes and sizes: small, large, extended length and double torsion springs can all be manufactured to our customer’s specific requirements. Our torsion springs are made in dimensions of 0.3mm to 8mm with wire, and the body diameter, length, pitch and choice of material are all down to customer specifications.
If you’re looking for standard torsion springs in the fine to medium weight category, you can find the specifications you’re looking for in our Spring Catalogue. Alternatively, we can manufacture torsion springs customised to your specific requirements, meaning they will not be found anywhere else and are unique to your design.
The speed of our production of torsion springs is one of the fastest of all our special products, as these types of springs only require one type of machine for production, so there is no finishing involved. European Springs can offer any conceivable end design and can even design completely new customised end designs if necessary. Get in touch today to begin the process, and don’t forget we have the same services available for all our other products, including compression springs and tension springs, so you can get everything you need directly from us.
