Springs are an essential component used in various industries and everyday objects, serving multiple purposes. They are mechanical devices designed to store and release energy when subjected to external forces or loads. In this article, we will explore different types of springs, their characteristics, uses, and the manufacturing process.

1. Compression Springs:

Compression springs are widely used due to their versatility. These springs resist compression exerted along their axis by pushing back against a force. Common applications include automotive suspensions, engine valves, mattresses, trampolines, and more. Manufacturing these springs involves coiling wire tightly around a cylindrical mandrel, ensuring precise diameter distribution throughout the spring's body while maintaining consistent pitch and tightness.

2. Tension Springs:

Tension springs, also known as extension springs, work opposite to compression springs. They generate resistance when stretched, exerting a pulling force upon release. Examples can be found in garage doors, hand tools, toys, and countless other products requiring tension. To manufacture tension springs, manufacturers wind wires closely together with hooks formed on each end, ensuring accurate alignment and appropriate tension is achieved during production.

3. Torsion Springs:

Torsion springs operate through twisting motion. They store and release rotational energy when subjected to torque or torsional stress. These springs find extensive use in clipboards, clothespins, door hinges, and various industrial equipment. Creating torsion springs involves coiling wire into parallel sections and attaching two legs at either end, allowing rotation to produce the desired effect.

4. Constant Force Springs:

Constant force springs provide uniform linear force when extended. Typically made from pre-stressed strips of steel, they offer consistent tension over prolonged periods. These springs often feature a flat spiral design that delivers continuous and reliable performance. They are commonly employed in office supplies such as retractable pens, tape measures, and window blinds.

5. Belleville Springs:

Belleville springs, also known as disc springs or conical washers, possess a unique shape with high energy storage and moderate deflection capabilities. These springs are stacked to create specific load capacities, resisting axial compression or tension with their ability to deflect, while maintaining an almost constant force. Belleville springs can be found in clutch systems, shock absorbers, valves, and construction machinery where precise pressure regulation is crucial.

6. Wave Springs:

Wave springs are engineered with multiple waves along the circumference, allowing them to provide substantial thrust within limited spaces. They offer comparable strength to traditional coil springs but occupy significantly less radial space. Common applications include aerospace components, medical devices, pumps, and motors where compact design is essential.

7. Gas Springs:

Gas springs utilize compressed nitrogen contained within a cylinder to generate controlled forces. They feature adjustable damping qualities and are commonly used for opening hatches, doors, lids, and ergonomic furniture. Manufacturing gas springs involves precision-engineered components that guarantee smooth extension and retraction movements, ensuring reliability and longevity of use.


Springs play a pivotal role in various industries, contributing to the function and performance of countless products we encounter daily. Whether it's compression, tension, torsion, or specialized types such as constant force, Belleville, wave, or gas springs, each type serves a specific purpose and offers distinct characteristics to cater to different requirements. Understanding the intricacies involved in manufacturing these springs allows us to appreciate their importance and relevance across numerous applications. CNC Milling
