Springs are available in different styles. Extension springs, for instance, are characterized by a coiled wire construction that becomes longer under a load, whereas compression springs are characterized by a coiled wire construction that becomes shorter under a load. In addition to coiled wire styles such as these, however, there are flat springs.
Flat springs aren’t made of coiled wire. Instead, they are typically made of flattened metal, such as spring steel. Like all springs, flat springs store mechanical energy. When exposed to a load, they will compress and deform while simultaneously storing the load’s energy. So, what are the benefits of flat springs exactly?
Compact
One of the main benefits of flat springs is their size. They are smaller and more compact than traditional coiled wire springs. They perform the same task of storing mechanical energy as coiled springs but consume a fraction of the space. As a result, flat springs are often used in applications where space is limited, such as machinery, furniture and medical equipment.
Lightweight
Flat springs are also lightweight. They weigh less than coiled wire springs. With their lightweight design, they reduce the overall weight of the machine or equipment with which they are used. This makes flat springs particularly useful for automobiles, aircraft and other types of vehicles.
Customizable
You aren’t limited to any single shape or size when using flat springs. Rather, they are customizable to meet the needs of the specific applications for which they are used. Some flat springs are circular, whereas others are shaped like a clover leaf. You can also find them in different styles, such as cupped, wave and curl. Regardless, flat springs are highly customizable.
Durable
You can’t rest assured knowing that flat springs are durable. They can typically handle hundreds of thousands of deformation cycles. Most flat springs are made of steel, which is known for being strong and resilient. To further protect against damage, though, some flat springs are coated in zinc. This zinc shell or outer layer protects the underlying steel from corrosion, allowing flat springs to be used in humid or moist environments.
In Conclusion
Fat springs offer a unique combination of strength, versatility and efficiency. Their compact size and light weight make them ideal for tight spaces, while their customizable shapes and durable materials allow them to perform reliably in demanding environments. Whether used in medical tools, industrial machinery or automotive components, flat springs deliver consistent performance without taking up unnecessary space or adding extra weight.
