With the help of the latest computer aided design software and specialised spring data, William Hughes used its knowledge and experience to develop a spring that was optimised for the application. In this instance a single torsion spring provided the best solution and William Hughes was able to quickly produce prototype springs for evaluation before the design was finalised for volume production.

Torsion springs provide a perfect solution for many automotive applications. They can be either single, which gives a higher force in a smaller space, or double, which provides a balanced force or torque. To overcome friction, which can be a problem in some applications, springs can be coated with special materials or the spring geometry can be optimised to minimise the effect. Other options include tension or compression springs in a range of sizes and materials.

In addition to special springs for car interiors, William Hughes can also supply a wide range of bent wire forms and sub assemblies for car seats and trim panels. Seat frames are welded or clipped together and supplied as complete pre-assembled units. These rigid assemblies are ready for immediate use to suit the requirements of the foam moulding process.
