Mechanical Compression Springs

Compression springs are helical, or coiled, springs that generate resistance to axially applied compressive force and store energy. Although they come in a standard shape, compression springs can be coiled by compression spring manufacturers into a number of different shapes.

There are cone-shaped compression springs, concave, or barrel-shaped compression springs, and convex or hourglass-shaped compression springs. There are small compression springs and larger compressions springs. Other, related shapes, as well as heavy-duty compression springs, are also possible depending upon the buyer’s needs.

Compression springs can also be left-hand coiled or right-hand coiled, indicated by the way the coil is bent. Which way the spring is coiled typically is not an issue, but nested springs should be coiled in opposite directions.

How Do Compression Springs Work?

The distinction between compression springs and other types of springs is that they are designed to bear a load that compresses the spring, causing the spring to get shorter and increase in tension as it stores more mechanical energy. Some types of products that can make use of compressions springs include firearms, trampolines and pogo sticks.

Different compression spring manufacturers may use different kinds of metals. For example, a manufacturer may use pre-hardened metal to wind small compression springs, while they may use softer metal for larger ones and harden the metal after winding. Compression springs that need to be especially resistant to corrosion may be made of galvanized wire, while those that need to carry electrical current may be made from beryllium copper.

IDC Spring can help you determine what your specific compression springs needs will be.

Measuring Your Compression Springs

When measuring compression springs, the important parameters to know are free length and pitch. Free length is how long the spring is when unloaded, without any compression placed upon it. Pitch is the distance between the centers of two adjacent coils.

There’s also a variety of ends to consider with compression springs. Your spring ends can be plain ends, squared ends, plain ends ground or squared ends ground. Again, our experts are standing by to help you determine which are the right ends for your compression springs.
