What is the Principle of Damping Hinge? How to Install the Damping Hinge?


The soft close hydraulic hinge has a good cushioning effect and is a noise-absorbing cushioning hinge. It can reduce the impact force when the door is closed. Even if the door is closed with force, it will not make a huge noise. Because it is practical and makes less noise, many people choose to use damping hinges to connect doors, wardrobes, bookcases, TV cabinets and other cabinet doors when decorating the home. So what is the principle of the soft close hydraulic hinge? How to install it correctly?


1. What is the principle of soft close hydraulic hinge?


The soft close hydraulic hinge is a kind of hinge, also known as hydraulic hinge, which refers to a noise-absorbing cushioning hinge that provides an ideal cushioning performance using the cushioning effect of liquid. It relies on a completely new technology to adapt to the closing speed of the door. The door slowly closes by itself at 60°, reducing the impact force and forming a comfortable effect when closing. Even if you use force to close the door, it will close gently, ensuring perfect movement and quietness. In mechanical physics, the reduction of the energy of the system--damping vibration is not all caused by "resistance". As far as mechanical vibration is concerned, one is the generation of heat due to frictional resistance, which reduces the mechanical energy of the system and transforms it into the internal energy. This kind of damping is called friction damping; the other is that the system causes the surrounding particles to vibrate, so that the energy of the system gradually radiates out to the surroundings and becomes wave energy. This kind of damping is called radiation damping.


2. How to choose the right soft close hydraulic hinge


Because the quality of hydraulic hinge depends on the sealing performance of the piston, there is no way for consumers to distinguish it in a short time. If you want to choose a good quality soft close hydraulic hinge, you need pay attention to:


(1) Appearance. The products produced by the mature door hinge supplier will pay more attention to the appearance, and they will be treated well on the lines and surfaces. Except for general scratches, there are no deep scratch marks. This is technical advantages of powerful manufacturers.


(2) The speed of closing the door is uniform. Pay attention to whether there is unsmooth part when opening and closing buffer hydraulic hinge. If you hear a strange sound, or the speed difference is too large, pay attention to the difference between the hydraulic cylinders.


(3) Anti-rust performance. Its anti-rust ability can be seen by salt spray test. Generally, rust will rarely appear after 48 hours.


3. How to install the soft close hydraulic hinge?


(1) Full cover


The door completely covers the side panels of the cabinet, and there is a gap between the two so that the door can be opened safely. Straight arm is 0 mm.


(2) Half cover


In this case, the two doors share one side panel. There is a required minimum total gap between them. The covering distance of each door is correspondingly reduced, requiring the use of hinges with bent arms. The middle curve is 9.5 mm.


(3) Built-in


In this case, the door is located inside the cabinet, next to the cabinet side panel. It also needs a gap so that the door can be opened safely. A soft close hydraulic hinge with a very curved hinge arm is required.
