Automotive coil springs are much more common in modern cars. They provide excellent shock absorption and ride comfort. Their strong performance has earned them a place in automotive suspension systems. In addition, door locks, shocks, spring mounts, brakes, etc. all require springs as important parts.

Toys are also an important application area for springs. For example, spring toys, pressure-reducing spring toys, flying trampolines, etc. are inseparable from the role of springs.

Medical guidewires（Flat springs）are commonly used to guide other medical devices such as catheters, stents, and medications into the body for the purpose of treating disease or relieving symptoms.
