As leading torsion spring manufacturers with a 170 year manufacturing legacy we have heavily invested in hot and cold coil wire forming facilities to meet the demands of our customers and fulfill the production requirements from our skilled workforce.
Advanced CNC coiling and grinding machines deliver quality, accuracy, the best production run rates and efficiencies across an extensive wire range.
In-line shot peening facilities improve components shelf life and fatigue performances
Large-scale, fully automated powder coat lines offer a zinc phosphate coating option in advance of powder coating, delivering 1000 hours of corrosive salt spray resistance.
Extensive training with industry specialists and through the Institute of Spring Technology, as well as through our own in-house training centres, ensures our team excel at the torsion spring manufacturing process.
Material specifications are the same as for compression springs, covering a wide range from:
Stainless steel torsion springs are one of our most common torsion spring material requests from customers.
Our material scientists are on hand to discuss the environmental need and application of your coil spring and therefore the torsion spring material's disadvantages and advantages.
A very high yield type of material (able to withstand high amounts of stress and maximum load) is best suited for torsion springs and as stockists of the largest global supply of chrome silicon wire, we’re confident in our supply and range of material choices suited to your torsion spring material.
Torsion spring design is often led by a force specification rather than a torque specification. The torque, needed to design the spring, can then be calculated by multiplying the force (F) by the length of the lever (leg end) that the force is acting on. Our experts master the maths, physics and manufacturing to deliver the measurables required for the application and are there to consult on the processes involved to ensure the outcome delivers and excels at the performance required.
Ensure your spring is completely ‘unwound’ before measuring the length as a torsion spring will be longer when installed and in use.
Using a digital vernier caliper, measure the spring wire diameter, then the outside diameter of the coils, count the number of coils and measure the dimensions of the leg length.
Our engineers would be happy to help you measure the helical coil diameter, maximum load, and leg angle and decide what material would best suit your spring. Please feel to contact our team for more information.
Once we’ve designed, manufactured and dispatched your product, the install element is individual to need and we suggest you visit YouTube to discover hands-on applications of torsion spring installs.
