If you open anything with a mechanism, you most likely will find a spring of some kind. A majority of battery holders contain springs to improve contact and maintain it in place. Almost every engineering product, from domestic to massive industrial processes, uses mechanical springs in some form or another.


Understanding Mechanical Spring

A mechanical spring is made from a metal wire spring that works as part of a spring mechanism to compress, stretch, spin, slide, tug, and apply force in response to an equal or larger force. A spring mechanism has a variety of ways to provide pressure, rotating force, and pulling strength. It is an instrument that transforms into a different shape in response to an external force and snaps back into place when the force is released.

The spring stores the energy absorbed, which can be released when it assumes its natural form. Foshan Gonglian Metal Products Co., Ltd. has been in the metal-making industry for ages and has managed to produce a variety of mechanical springs.

Types of Mechanical Springs

Spring types can be divided into categories depending on how the force is applied or exerted.

·         Compression springs

·         Torsion springs

·         Constant force springs

·         Extension springs

Application of Compression Springs

Compression springs are constructed or coiled to resist compression along the spiral axis. A helical compression is the most typical type of metal spring design. The coil springs can operate independently despite frequently being built over a rod or placed into a hole.

Compression spring uses involve:

·         Automobiles: It would be quite challenging to produce most cars without using compression springs. In automobiles, compression springs are utilized in various components, including chassis, hoses, and seats.

·         Door locks: Due to the locking and key system's function, which depends on the key to relieve the pressure stored, most metal locks have some steel springs. The tension needed for this is produced via spring compression.

·         Pen: The pen can write with the tip exposed thanks to this spring, which then covers within the housing to prevent ink from drying out.

·         Firearms: A spring compresses to take the energy from the recoil and direct it toward moving, reloading the weapon for the next shot.

Application of Torsional Springs

Technically, torsion springs are devices that are specially designed to absorb energy- rotational energy. At either end, the spring is connected to a mechanical component. The more radially you twist a tension spring, the more force it produces. This implies that the force you exert will increase. Garage doors, lift doors, shutters, controlling levers, spring hinges, and various torsion uses are all possible with torsion springs.

Application of Constant force springs

It is formed from a flat, pre-stressed springy material wound almost uniformly around itself or a drum. Like a typical extension spring, the strip's intrinsic strain resists the load force when stretched. Constant force springs are used in various long-motion components, including counterbalances, tool head returns, door closers, hose retrievers, cable retractors, and space vehicles.

Extension Springs

Extension springs are designed with two main functions in mind. They can either work to absorb and store energy or to resist pulling forces. When coiling the wire, the wire is spun counterclockwise during manufacture, which results in the "initial tension."

Extension springs are used in countless products, such as cars, indoor and outdoor, door assemblies, pliers, engine components, trampolines, washing machines, farm equipment, toys, and more.

Advantages of Mechanical Springs

Better Absorption of Shock

Springs are used widely in various devices. This is mainly because they can absorb shocks, and, as a result, lessen the effects of weight and tension. Typically, the springs compress and decompress to absorb shocks when applied to the product. This makes them crucial components of automobiles.

Acts as an Energy Reserve

Spiral springs are, undoubtedly, the best illustration of a spring that can replace a battery. These springs are specially designed to continuously produce energy with their application of force. As a result, they are perfect for the manufacture and running of mechanical watches.

Criterion of Functionality

Thanks to the criterion of functionality incorporated in springs,  two pieces of a product or item can be joined together. For instance, it is quite easy to join two elements for weighing machines, garage doors and garage doors using a spring.


This is yet another important factor in springs. Their ability to absorb shock helps to assure the stability of the products that depend on them to function. Besides, resistance and vibration can also be minimized by increasing product stability.


Springs are, undoubtedly, crucial components of most products, especially those that involve moving parts. They are designed to hold and release energy while also compressing and expanding. For this reason, knowing the types of springs available nowadays can help you choose the best spring.

But you should note that each spring has unique qualities and properties. And, therefore, ensure you put into consideration the above factors when deciding to use a spring for your product.
