Wave springs are some of the most widely used types of springs, but often, we don’t even realise that we are using them.
Most commonly found in circumstances where space is limited, wave springs are essential to many components in the world of mechanical design. They must be compact, provide ample force and be able to withstand immense pressure over a long periof of time to be effective.
 What are wave springs?
Wave springs are a type of compression spring made from flat wire. They are called wave springs as they have multiple waves per turn. The flat wire, along with multiple waves, combine to create the same amount of force at reduced work heights when compared with other types of springs.
With technological developments meaning that many devices that once used compression springs have shrunk in size, the need for smaller, more compact springs has grown. The reduced size has allowed engineers to reduce the spring cavity once common in many technologies.
 How are wave springs made?
In a similar method to many other types of spring, flat wire is passed through a specially-calibrated machine where it coils and ‘bounces,’ resulting in a wave spring. The machine is set up to process the wire up to a certain length, providing a system that can be tailored to any given project or requirement, and reducing waste.
 Properties of wave springs
Wave springs are versatile; they hold many advantages that maintain their popularity with designers. For example, where space is limited, the innovative design of the wave spring ensures that the same amount of force as a compression spring is produced at 50% of the operating height.
Due to the layered design, only one spring is needed, whereas with alternative springs, such as stacked disc springs, several are needed to provide the same effect. In addition, the design of the spring can be amended to reflect whatever the task requires. For example, factors such as wire size, wire form and the turn configuration can all be altered to ensure that the end result is fit for purpose.
 Common uses of wave springs
Due to the fact that wave springs can be substituted for compression springs, they are regularly used in a number of daily item:
- Door locks
- Suspension systems
- Mechanical equipment
- Technological devices
- Medical products
- The oil and gas Industry
