COMPRESSION SPRING

Compression springs are helically wound wires with pitch in between each coil in order to store and release force/energy when compressed and released. They are made to have memory so once a load/force is released, they will return to their original length.

Compression is the ability to make something more compact. Compression springs are very versatile creations and are considered reliable, efficient and reasonably cheap to produce. They are made in high quantities every year and are available in an assortment of shapes and sizes to be used for a variety of functions.

To consider the specifications you’re going to need when manufacturing your compression springs, you’ll need to consider the wire diameter, outer diameter, inner diameter, solid height, and free length that you’ll need for your specific application. The free length is described as the spring’s overall length in the unloaded position, while solid height refers to the length of the spring under sufficient load that brings all of its coils into contact.

You’ll also need to know which spring rate, or stiffness, you’re going to need. This is the change in load per unit deflection in Newtons per millimeter or in pounds per inch. These dimensions and the load/deflect requirements will determine the stresses of the compression springs. Getting these stresses calculated properly is vital to the optimal performance of your springs. The design must be calculated based on your specific application in order for your springs to work correctly
