Lee Spring Ltd - Plastic Springs

We offer plastic springs combining the strength of metal and the features of high performing engineered thermoplastics.

With a wealth of engineering experience, design and research, we have developed this compression spring offering. Our plastic springs have a variety of uses in the medical, pharmaceutical, imaging, aerospace, and electronics sector.

They are also ideal for pollution control systems, automotive interiors and chemical environments.

Plastic springs benefit from corrosive-resistant properties, stability, maximum strength and low flammability.

Our custom springs are designed and manufactured for your precise requirement. If you send us a drawing of the specifications you require, including quantity and load requirements then we can produce your custom springs.

Our custom designs can be produced in a range of alloy metals such as stainless steel, phosphor bronze and copper. They can be designed with range of diameters, widths and thicknesses.

Compression springs are open-coil, helical springs manufactured to oppose compression along the axis of wind. As the most common metal spring configuration, they can be placed inside a hole or over a rod.

When loaded, compression springs push back against the load and attempt to get back to original size. Our compression springs have ground and square ends. They are ideal for high duty springs, close load and rate tolerance, accurate seating and buckling tendency reduction.  

We supply compression springs for use in stamping presses, automotive engines and medical devices.

We supply Redux wave springs that can replace compression springs in applications where a tight load deflection is required in a small space. They can reduce the weight and size of the assembly by a substantial 50 percent.

We manufacture our wave springs in Type 17-7 stainless steel flat wire in a continuous coil with regular waves and diameters.

Our hefty die springs are offered at unbeatable prices offering you an exceptional value package.

The unique benefits of hefty die springs include shot peened to extend the life of the spring, preset to prevent length loss and powder coated in colour for easy identification.

They can also be supplied with square or ground ends and are perfect for aircraft mechanisms, farm machinery, brakes, and clutches.

Torsion springs are used to attach a component at each end and rotate the component around the centre of the spring. The spring tries to push them back to their original place. They are susceptible to bending stresses and angular energy.

Torsion springs can be used in applications such as clipboards, swing-down tailgates, garage doors and clothes pegs. They can range extensively in size, from large springs used in chair control units to small, intricate springs for use in the electronics industry.

Our extension springs for perfect for use in vise-grips, pliers, trampolines, washing devices, and garage door assemblies.

Extension springs can also be integrated into products like farm machinery, automotives and a variety of toy designs.

Our Belleville washers are manufactured with small deflections with high support loads and solid heights.

Belleville washers are an ideal solution for vibration thermal expansion, bolt creeps and relaxation. Belleville washers can also be stacked for additional load flexibility.
