What is the difference between a gas spring and a damper?


In the process of furniture design and manufacturing, both pneumatic and hydraulic technologies are widely used. These technologies are very common in furniture manufacturing because they can help speed up the manufacturing process, increase efficiency, and reduce labor costs. In addition, these technologies can also improve the quality, functionality, and durability of furniture, increasing user comfort and satisfaction.

Pneumatic technology is mainly used to manufacture furniture components such as chairs, sofas, seats, etc. The principle is to use the power of compressed air to process and accelerate the manufacturing process. Compressed air is delivered to the cylinder, and the piston drives the machine to work. Hydraulic technology is mainly used to manufacture various adjustment mechanisms and telescopic mechanisms, such as lifting tables, lifting chairs, sofa chairs, etc. Its principle is to use the hydrostatic pressure of liquid and the principle of fluid mechanical transmission to control and adjust various motion states of machinery.

Among furniture hardware accessories, gas springs and dampers are common components used in furniture. They all have their own different characteristics and functions. Here, we will detail the similarities and differences between gas springs and dampers.

What is the difference between a gas spring and a damper? 1

Gas spring

A gas spring is a device that generates force by compressing a polymer gas. It is an adjustable mechanical element, usually consisting of an annular and shortened inner and outer barrel, with a resistance adjuster that adjusts the resistance it produces to have different compressive and elastic characteristics.


Gas springs are used in a wide range of fields, especially in industrial automation, automobile production, furniture and home appliances. It has the following characteristics:


1. Strong stability. Because the gas inside the gas spring is compressed and deformed, the greater the internal pressure, the greater the reaction force it will generate. At the same time, the gas spring also has an adjustable air regulator, which users can adjust according to their needs.


2. Good durability. Most gas springs are made of high-strength materials, can withstand a high load, and have a very long life.


3. Easy to install. Gas springs are relatively simple to install due to their relatively small size and the fact that they require no fluids or electricity.

A damper is a device used to slow the motion of a moving element by counteracting the momentum to slow or control the speed. In furniture manufacturing, dampers are mainly used for objects with gravity such as doors and drawers.


Dampers can be divided into hydraulic and magnetic dampers.


The hydraulic damper is a damper that uses the friction generated by the movement of the liquid to slow down the movement. Its principle is to let the oil enter the hydraulic chamber through specific bullet holes to generate pressure resistance, thereby adjusting the speed.


A strong magnetic field is used in the magnetic damper. By using the principle of mutual repulsion of the magnetic field, the movement speed of the mechanical equipment is slowed down, and the control ability of the heavy object is improved.


Compared with the gas spring, the damper is a safer device. This is because the damper can not only control the movement speed of the object, but also control the movement time, maintain a certain stability in the whole process, reduce the probability of accidents, and at the same time reduce the damage to the machine.


The difference between gas springs and dampers


From a practical point of view, both gas springs and dampers are devices that can control the speed and stability of actions. However, in terms of practical scope and function, gas springs and dampers are still different.


Gas springs are used in a wider range and are used in many fields such as furniture and automobiles, because they can provide compressed gas with different resistances, reduce the speed of movement of objects, and play a role in slowing down the movement. At the same time, because of its relatively high degree of freedom, it can be adjusted and used according to user needs.


The damper is more suitable for controlling the movement speed and stability of heavy objects such as doors and drawers. The damper can not only accurately control the movement speed and acceleration process of the object, but also ensure stability during the movement and reduce the occurrence of accidents. Therefore, it is widely used in furniture manufacturing to ensure the stability and safety of furniture in use.


In general, gas springs and dampers are very important items in furniture hardware accessories. Although they have slightly different functions and functions, they are all for better performance and user experience of furniture, and to improve maintenance, etc. efficiency, and convenience. We believe that with the advancement of technology and the continuous expansion of application fields, the application of gas springs and dampers will become more and more extensive, and will also have a more extensive and far-reaching impact in the future furniture manufacturing field.


Both pneumatic and hydraulic technologies have their own unique advantages in furniture manufacturing. When choosing which technology to use, the most suitable technology should be selected based on the nature of the furniture and the manufacturing process in order to provide a better user experience, reduce manufacturing costs, and at the same time improve production efficiency and manufacturing quality.
