Springs are fascinating mechanical devices that play a significant role in various industries and applications. They are versatile, elastic objects that store mechanical energy and release it when subjected to a force or load. This article aims to shed light on the different types of springs, their uses, and how they are produced.

1. Torsion Springs:

Torsion springs are known for their capability to resist rotary motion. These springs operate by exerting torque in response to applied rotational forces. Commonly found in door hinges, clothespins, and mousetraps, torsion springs provide the required tension to hold doors closed or return them to an open position once released. To produce torsion springs, manufacturers use CNC machining techniques to precisely shape the wire while ensuring optimal flexibility and durability.

2. Compression Springs:

Compression springs are among the most widely used types of springs. They are designed to compress under a load and subsequently push back against it, providing resistance and storing potential energy. You can find compression springs in everyday items such as mattresses, pens, switches, and even shock absorbers. The manufacturing process involves shaping a metal wire into a helical coil using CNC machining, ensuring precise dimensions and uniformity in each turn.

3. Extension Springs:

Extension springs function oppositely to compression springs. They extend under a pulling force and absorb energy when stretched. Extension springs are commonly employed in trampolines, garage doors, and balance scales. Using CNC machining, these springs are fabricated by tightly coiling a wire, allowing for controlled stretching and improved elasticity.

4. Constant Force Springs:

Constant force springs are unique in their design, offering a consistent amount of force throughout their entire range of extension. They are utilized in retractable ID card reels, window blinds, and tape measures. Creating constant force springs requires precision engineering where a strip of ribbon-like material is tightly wound onto a drum, which then provides the desired linear force.

5. Tension Springs:

Tension springs, also known as traction or drawbar springs, are designed to operate with tension rather than compression. They are often found in garage doors, suspension systems, and various mechanical devices. These springs function by absorbing or exerting an equalized amount of force across their coils while being stretched. Precision manufacturing using CNC machining ensures that tension springs provide reliable performance and return to their original length when the load is removed.


Springs come in numerous forms, each catering to specific applications where their unique properties and functionalities are of utmost importance. From torsion springs that resist rotational movements to extension springs that stretch under tension, these versatile mechanical components find use in countless industries and everyday objects. The production of high-quality springs relies heavily on precision engineering techniques like CNC machining, ensuring dependable performance, durability, and optimal energy storage capabilities. Understanding the different types of springs and their uses enables us to appreciate the significance of these remarkable devices in our daily lives. CNC Milling
