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

· Torsional springs

· Constant force springs

· Extension springs

Application of Mechanical 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


A torsion spring is a device that absorbs 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 have two main functions: they work to resist pulling forces by absorbing and storing energy. 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


Greater Absorbency of Shock


Springs are used widely in various devices because they can absorb shocks to lessen their effects. The springs compress and decompress to absorb shocks when applied to the product. Consequently, springs are crucial components of automobiles.

Acts as an energy reserve


A spiral spring is the best illustration of a spring that can replace a battery. The spring can continuously produce energy with the application of force. Thus, it's a crucial part of making and running a mechanical watch.

Associated Mechanism


Two pieces of a product or item can be joined together using a spring. For instance, to function, springs unite two elements for weighing machines, garage doors and garage doors.



The ability of springs to absorb shock helps to assure the stability of goods that utilize them. Part resistance and vibration minimization can also be accomplished by increasing product stability.



Springs are a crucial component of most products or components that move. They can hold and release energy while compressing and expanding. Knowing the types of springs available nowadays can help you choose the best spring. Each spring has unique qualities and properties. Therefore, it is best to consider the above mentioned aspects when deciding to use a spring for your product.
