Self Closing Hinges

Self closing hinges are an innovative door hardware that allows doors to close more smoothly without the need for traditional hydraulic door closers. Self-closing hinges have a compact design that combines door closer, door stopper, positioner and shock absorber in one body.

Eliminates the levers of unsightly hydraulic closers that are not compatible with later systems such as wire gates. Its simple and beautiful design is compatible with different door styles.

Soft Closing Hinges

Additionally, they can offer a slow-close feature; however, not all self-closing hinges may have a slow closing feature.
They are generally of two types; spring hinges and hydraulic hinges. Spring hinges do not have a slow closing feature as well as self closing. Hydraulic hinges can have both features depending on their construction features. Or it can only be used with self-closing spring hinges with its slow closing feature. In this case, the door to which the application is made has a self-closing feature and a slow closing feature.

In systems where both spring hinges and hydraulic hinges are used in combination, the spring hinge closes the door and the hydraulic hinge acts as a buffer and performs the slow closing task.

Hydraulic hinges & spring hinges

The combination of spring hinge and hydraulic hinge allows even heavy doors to work with desired features. At the same time, it has a high advantage over other systems as it provides very easy adjustment.
Our spring hinge does not require any adjustment and our hydraulic hinge has only one adjustment for the slow & soft closing feature. Therefore, easy to install, even easier to set up.


  • This product is used as a combination of hydraulic hinge and spring hinge, and according to the type of hinge, there are right and left hinges used during assembly.
  • Automatic door closing speed can be adjusted. The closing effect is slow and gentle; quiet, in addition secure and jam-free.
  • The maximum opening angle is 180° in one direction; If the angle is less than 80°, the door will close automatically and softly.
  • Free door stop angle: 180°- 80°; fast closing angle: 80°- 30°; slow closing angle: 30°- 10°; latching angle: 10°-0°.

How do hydraulic hinges work?

Hydraulic Power: When the hinge is opened, the bending deformation of the torsion spring, produces a backlash & closing force. A small oil cylinder is placed on the hinge shaft, and this piston with oil return hole, slides back and forth along the wall of the oil cylinder to generate hydraulic pressure.

Damping: When the hinge is closed, the pressure created by the bending of the torsion spring forces hydraulic oil in the cylinder to flow through the small hole of the piston. The oil flow rate is low due to the small diameter of the oil hole. Therefore, the torsion spring is prevented from closing the door quickly, thereby damping or buffering the closing speed.
