USA patent granted for Lee Spring's plastic springs

One of the world's leading manufacturers of mechanical springs, wireforms and stampings, Lee Spring received the new US patent No 8,939,438 B2, dated 27 January 27 2015 and titled Plastic spring and method and apparatus for making the same.

Designed and manufactured from plastic material, the helical springs feature a design not normally available in a conventional metal spring. Known as LeeP Plastic Composite Springs, the series of stock and custom plastic composite springs offered by Lee Spring are non-magnetic with high corrosion resistance, high strength-to-weight ratio and they are designed to minimise the solid height of a fully compressed spring. These plastic springs have been designed to suit a number of different applications including non-conductive applications, or applications where a metallic spring is just not suitable.

Lee Spring continually strives to look for new ways to innovate in an industry where spring designs and manufacturing methods have remained relatively stable over a long period of time.

Chris Petts, Managing Director of Lee Spring in the UK, comments: "We have been manufacturing springs for nearly 100 years, yet we are constantly presented with new challenges in the market and new design criteria and parameters to meet. We are always looking for new ways to satisfy our customers' unique requirements. The Leep Plastic Composite Spring, for example, was a product born out of a market need. We looked at something we do every day in a new and innovative way."
