Springs play a crucial role in many industries and applications, often serving as essential components that provide flexibility and support. From simple mechanical devices to advanced machinery, springs are used in numerous ways to store and release energy. This article aims to explore the different kinds of springs, explaining their types, functions, and manufacturing processes.

1. Compression Springs:

Compression springs are the most common type of spring and widely used across various industries. These springs absorb or apply force when compressed, allowing them to return to their original form once the force is released. Compression springs find application in automotive suspensions, mattresses, valves, and more. Their production involves shaping tempered steel wire into cylindrical shapes using CNC machining techniques.

2. Tension Springs:

As the name suggests, tension springs work by stretching rather than compressing. They possess an extended loop or hook at both ends, generating resistance against forces pulling on the ends. Tension springs can be found in trampolines, garage doors, balances for weighing scales, and other applications where load-bearing capacity is required. Manufacturing these springs typically involves winding steel or stainless-steel wires tightly around a mandrel using precision CNC machines.

3. Torsion Springs:

Torsion springs operate by exerting twisting motion instead of compression or tension. They store rotational energy when twisted, releasing it when untwisted. Common examples include clothespins, hinges, garage door openers, and mouse traps. To produce torsion springs, manufacturers use CNC machines to coil and shape wires with specific diameter and pitch requirements based on the intended application.

4. Constant Force Springs:

Constant force springs are unique due to their ability to maintain consistent force throughout their deflection range. The flat strip-shaped spring maintains its spiral-like shape during operation and features smooth extension and retraction properties. These springs are commonly employed in retractable tape measures, window blinds, and automotive seatbelts. Their production involves precisely forming the flat strip of steel using specialized CNC machines.

5. Belleville Springs:

Belleville springs, also known as disc or conical springs, are cone-shaped and primarily used to handle high loads while maintaining accurate load deflection characteristics. These springs excel in applications requiring high spring rates and limited space availability. Common uses include control valves, electrical connectors, clutches, and pressure relief systems. The manufacturing process involves precision cutting and shaping of stainless-steel discs using advanced CNC machining techniques.

6. Wave Springs:

Wave springs are a type of compression spring characterized by their wave-like shape, providing high forces within a small axial space. They are typically made from spring steel strips wound into a spiral pattern. Wave springs find usage in various industries like aerospace, medical devices, and automotive assemblies where compactness is critical. Production involves CNC machines accurately shaping the steel strips into the desired wave pattern.


Springs are vital components in many mechanical systems, enabling movement and absorbing shock or energy for countless applications. Understanding the different kinds of springs, including compression, tension, torsion, constant force, Belleville, and wave springs, allows designers and manufacturers to select the most suitable option for specific needs. With the continuous advancement of CNC machining techniques, producing these springs has become more precise, efficient, and reliable, meeting the diverse requirements of modern industries.
