Springs play a vital role in various industries, serving as mechanical devices that store potential energy. These versatile components have an extensive range of applications, from ensuring proper suspension in vehicles to facilitating smooth movements in precision machinery. In this article, we will delve into the different kinds of springs, their manufacturing processes, and some fascinating applications they find themselves in.

1. Compression Springs:

Compression springs are one of the most common types used widely across numerous industries due to their ability to absorb and store energy when compressed. They are typically produced by CNC machining equipment using high-quality materials such as stainless steel, brass, or titanium. The wire is coiled tightly with accurate measurements adhering to specifications before being formed into cylindrical shapes. Compression springs are utilized in automotive suspensions, heavy-duty machinery, valves, and even everyday items like pens and mattresses.

2. Torsion Springs:

Torsion springs operate on the principle of torque rotation and work by exerting rotational force when twisted or bent. These springs can be found in various mechanisms like doors, clothespins, mouse traps, and many other devices requiring rotary motion assistance. To manufacture torsion springs, narrow metal strips are wound tightly around a mandrel using CNC machinery, creating a helical form that returns to its original position after being rotated.

3. Extension Springs:

Extension springs are designed to extend when pulled or stretched and generate resistance against the load applied. These springs are predominantly seen in garage doors, trampolines, exercise equipment, and countless other applications where stretching forces need to be absorbed. CNC machines aid in producing extension springs by winding a coil pattern out of a strip of metal, ensuring precise dimensions and consistent performance characteristics.

4. Constant Force Springs:

Constant force springs differ from other spring types as they provide nearly constant force throughout their deflection. This unique characteristic makes them ideal for applications such as tape measures, window counterbalances, and roller shade systems. Manufactured by winding flat strips of material onto a precision reel, constant force springs require CNC machining to maintain precise geometry.

5. Wave Springs:

Wave springs, also known as wave washers or spring washers, are coiled springs with an innovative design that offers excellent load-bearing capabilities in compact spaces. They find widespread use in automotive suspension systems, clutches, valves, and electrical components, where space limitations dictate their usage. Utilizing CNC machining technology ensures accurate coiling and the correct number of waves per coil for optimal performance.

6. Belleville Springs:

Belleville springs, popularly known as disc springs, consist of conically shaped discs stacked together to generate high loads with small deflection ranges. These springs effectively handle heavy-duty applications like safety valves, bolted connections, and industrial machinery requiring large forces within confined spaces. CNC machining is essential to maintaining consistent dimensions during the manufacturing process, guaranteeing a reliable and resilient product.


From compression and torsion springs to extension and constant force springs, each type serves its unique purpose across various industries. The advent of CNC machining has revolutionized the production of these vital mechanical components, ensuring precise specifications, durability, and consistent performance. Understanding the diverse range of springs available empowers engineers and manufacturers to select the most suitable option for their specific application, unlocking enhanced functionality, efficiency, and safety.
