Types of Coil Springs: Extension and Compression Springs

Coil springs, or helical springs, are used to store and release energy. It is a simple mechanical device used to hold forces between contacting surfaces or to absorb shocks. Typically, coil springs are used in applications such as bouncers and shock absorbers for machines, or as a way to automatically close lids or doors after they have been opened. Typically, coil springs are made of an elastic material that can be stretched or compressed as needed to create a spiral shape. When stretched, the spring automatically returns to its original shape.

A coil spring consists of a metal wire coiled in a spiral form and is used primarily to carry compressive or tensile loads. The cross section of the wire used to make the spring can be round, square or rectangular. Helical compression springs have applications that resist the applied compression force or store energy in the push mode to provide push. Different forms of compression springs are produced.

Most coil springs are made of metal, but plastic coils are often used. A coil spring is a torsion spring because when the spring is extended or compressed, the spring generates a torsional force. Most springs are manufactured by winding metal wire around a formed cylinder, which provides the correct shape and tension for the spring based on the shape design.

Tension Springs

Tension springs are designed to resist stretching. Usually, they have a hook and eye on each end that allows them to be attached to another component. These springs are used to cushion or automatically close openings or to hold two objects together.

Uses.

●Trampoline

●Automotive interior and exterior trim

●Garage doors

●Farm tools

●Clamps

●Stretchers, surgical lights and other medical equipment

Compression springs

Compression springs are designed to resist compression. They are commonly used to absorb shocks from motors and other machines, including automobile suspensions.

Uses.

● Valves

● Locking doors

● Railroads

● Automobiles

● Electrical switches

● Large-scale stamping machines

● Ballpoint pens

Both types of coil springs are used equally in manufacturing and commercial applications. When purchasing a spring, it is important to consider a variety of variables. Examples include the desired configuration, the weight of the load, the required elasticity, and any regulations that must be followed. The right manufacturer will provide you with reasonably priced, precisely manufactured and uniform parts, whether you need a large number of coil springs or a small number of them. Also, look for companies that offer ideal services, such as ISO-compliant green manufacturing, lean manufacturing, ISO-certified manufacturing processes, AS9100-certified springs (for aerospace applications), and ISO-certified management systems.
