Types of Small Coil Springs
Before diving into where to buy, it's important to understand the types of small coil springs available on the market. The most common categories include
1. Compression Springs These springs are designed to compress under axial loads and return to their original shape once the load is removed. They are widely used in various applications, including automotive suspensions and industrial machinery.
2. Extension Springs These springs are made to elongate when loads are applied. They are often used in applications requiring a pull force, such as in trampolines or garage doors.
3. Torsion Springs These springs exert torque when twisted. They are commonly found in applications like clothespins and certain types of automotive mechanisms.
Understanding the specific type of spring you need will help narrow down your options when looking for suppliers.
