Overview: What are springs?

Technically speaking, springs are an elastic object that stores mechanical energy. In the manufacturing setting, the term coil springs are often referred simply to as springs. There are many types of springs in design, the common ones include compression spring, torsion spring, and extension spring. 

Compression spring

When one hears the word spring, they usually think of compression springs since they are the most common type of spring out there. One of the defining of this type of spring is that it provides resistance force to the pressure of the external load. They are usually made out of metal wires and have various applications in motors. There are many parameters before deciding which compression spring to choose from, and this includes things such as the elasticity, line diameter, coil number, center diameter and spring coefficient. These variables are used in the calculation of the stiffness of the spring.

Compression Springs

Torsion spring

The torsion spring is a variant of the spiral spring. What differentiates this type of spring from compression spring is the fact that they provide resistance to rotating external forces. The ends of this spring are usually attached to other components and will resist when external forces rotate around the center of the spring. It has application in many fields, such as computer, electronics, automotive, and other mechanical industries. The material used to create it would be different depending on the usage, therefore it is advised to consult with an expert.

Extension spring

The next type of spring would be the extension spring, which is also known as the pull spring. Unlike the previous two springs, this one bears the axial tension. The defining feature of this type is that in the absence of load, there is no gap between the ring and the ring of a stretch spring. It has application in medical breathing equipment, mobile control, shock absorber, pumps, and other mechanical components. Similar to the previous springs, the materials used to create such a spring would be highly dependent upon its usage, therefore it is suggested to first understand what the end-user is looking for. The necessary parameters to consider would be the free length, control diameter, wire size, material, number of cycles, the form of the end, load in the hook, load rate and maximum stretch length.

Other types of springs

Springs are not limited to the three types mentioned above. Other types would be die spring, circlips, disc springs, etc. Regardless of what springs you are looking for, it is highly advised to first understand your needs, and then assess whether the spring of your choice meets your needs.

How springs are made

One of the methods used to produce spring is by CNC Spring Coiling Machines.However, some other special springs are made by metal Stampings,such as disc springs,which is popular for induustry using too.
