Well, we’re going to look at something pretty nifty today, this thing called a flat spring clip. Have you ever seen a spring? You might have one in a pen or a toy! Now a flat spiral spring is unique because it appears to be a flat circle that has been twisted.
Flat spiral springs are produced in the form of a flat spiral, from a long strip of metal. This shape allows the spring to store energy when it is squished or stretched. When you release the spring, because of the energy you used to press it in, it returns to its starting shape.
Flat spiral springs are found in many things, such as clocks, watches and machinery in factories. They are heavily utilized because they can generate a great deal of force in a small space. That means they can be used in spaces where a larger spring would be too big.

Flat spiral springs have a nice property that they deliver a constant force. Which is to say, if you push down on the spring, it will push back with exactly as much force. This is critical for machines which must work correctly.

If you’re choosing a flat spiral spring for your next project, there are a few things to consider. You need to think about how big the spring is, how much force it can offer and how long it will hold up. You should also consider what the spring will be used for and whether it will be close to things like heat or water.

Flat spiral springs can be found all over the place — from airplanes to medical instruments. You can find them inside door hinges, automatic doors and robots! Companies are employing flat spiral springs in new and intriguing ways, such as robotic artificial muscles.
