Plastic Composite Compression Springs from Lee Spring

Increasingly, engineers are seeing the benefits of plastic spring technology as exemplified by Lee Spring in their LeeP™ Plastic Composite Series. By offering non-magnetic, non-corrosive and chemically inert properties in a lightweight package, LeeP™ springs are often ideal for applications in areas of medical device manufacturing, pharmaceutical equipment, aerospace and lightweight instrumentation.

The LeeP™ Plastic Composite Series combines the strength of metal springs with the attributes of high performing engineered thermoplastics – in this case, Ultem PEI (polyetherimide) resin. This material has excellent thermal stability and electrical insulation properties while being non-contaminating. They have low flammability and are recyclable in compliance with global regulations including RoHS and REACH.

LeeP™ Plastic Composite Springs are stocked in a variety of standard sizes, each available in a range of strengths formulated from different Ultem resins. The five increasing strengths are easily identifiable by distinct colors: Red, Orange, Yellow, Green and Violet. Lee Spring has the advanced technology to provide Custom LeeP™ Compression Springs to meet the most exacting specifications.

These plastic compression springs offer high strength to weight ratios that optimize performance while reducing mass; they have excellent stability of physical and mechanical properties at elevated temperatures up to 170°C; high corrosion resistance and are generally compatible with many chemicals including strong acids, weak bases, aromatics, and ketones. Their non-magnetic material does not interfere with imaging and other Ferro-sensitive technologies, making them suitable for non-conductive applications. The inert and non-contaminating plastic composite protects the purity of the products the springs come in contact with.

Other applications include: medical products and processing equipment, pharmaceutical delivery devices, imaging and X-Ray equipment, food processing and packaging equipment, aerospace products, marine products, electronics and electrical equipment, water purification systems, chemical environments, automotive interiors, pollution control systems, semi-conductors, instrumentation, communication devices, and cosmetics packaging equipment.
