SPLICE

Specialist Polymer Lightweight springs: Innovative processing using Conventional Equipment

Download the leaflet


About the project

The SPLICE project set out to determine whether lightweight polymer springs could be manufactured using existing conventional processes used to manufacture steel springs. Researchers at WMG, part of the University of Warwick, together with Force Technology, the Institute of Spring Technology (IST) and the Northern Automotive Alliance (NAA), won research funding worth £244,090 from Innovate UK for the project. The project has been led by the IST.

Benefits of polymer springs

Polymer production is less energy and raw material intensive than either silicon steel wire or titanium wire. Polymer springs can also be easily recycled at the end of their life.

Lightweight polymer springs have the potential to lower emissions and improve fuel economy in automotive applications. They could replace heavier steel springs in other sectors. Polymer springs are also corrosion resistant and can be used when steel cannot, due to their non-magnetic and electrically insulating properties.

Results

The SPLICE project was successful in proving that lightweight polymer springs can be manufactured using conventional processes, by modification of a manual spring coiler (found in many factories) with the addition of a heating stage. No significant new tooling was required, allowing cost-effective high-variety production at low to medium volumes. Initial testing shows that the polymer springs had very promising performance.

What next?

Additional research is needed to develop the optimum properties for polymer spring materials and applications. With further development, polymer springs could be used cost-effectively for a range of applications in the automotive, transport, aerospace, space, marine, oil & gas, electronic and medical sectors. This would result in new market  opportunities for the UK spring industry.
