Plastic composite compression springs

Jon Lawson

By offering non-magnetic, non-corrosive and chemically inert properties in a lightweight package, LeeP Springs are often a complete solution for applications in areas of medical device manufacturing, pharmaceutical equipment, aerospace and portable instrumentation.

The range combines the strength of metal springs with the attributes of high performing engineered thermoplastics – in this case Ultem PEI (polyetherimide) resin, which has excellent thermal stability and electrical insulation properties, while being non-contaminating. They have low flammability and are recyclable in compliance with global regulations.

LeeP plastic composite springs are stocked in a variety of standard sizes, each available in a ‘rainbow’ of strengths formulated from different Ultem resins. The five increasing strengths are easily identifiable by distinct colours: red, orange, yellow, green and violet. Lee Spring can provide Custom LeeP compression springs to meet the most exacting specifications.

Lee P springs offer high strength to weight ratios that optimise performance while reducing mass.
