Compression springs are open-coiled springs which are wound in a helical shape in a variety of cross-sections and forms for linear applications.
As compression springs are compressed to a shorter height, they provide a force (push) to return the spring back to its normal height. Typically they are cylindrical springs made out of round wire. However, they can be made conical, oval, barrel or virtually any other shape. The wire can be round, square or rectangular.
Compression springs are the most common spring configuration and are used in a wide variety of applications. They are found in products such as major appliances, automotive, aerospace, as well as consumer goods.
