Damper applications:
Rotary damper is widely used in all kinds of seats, including auditorium seats, cinema seatings, automotive seats, truck and train seats and many public seats. It also can be used in car interior, such as car CD, car mirror, car ashtrays, handle ect. And other application such as in trash can, coffee maker, electric kettle, washing machines, toilet seat and cover, window screen, many kinds machines, mechanical equipment, drawers, cabinets, furniture, stereo, beverage holder, caps, sunglasses, clothes rack, handle lamp box, locker or box, shutter, all kinds of small and medium-sized boxes flap.

It can slow down the vibration and reducing the speed of door opening and closing, make its smooth open and close, and reduce the noise in the process of product using effectively, can give customer good feeling when use the product with damper.
 
Our damper working principle:
This kind damper is made of body, rotor, and special silicon oil. Its torque made by rotor rotation, it is caused by silicon oil viscosity and contact area. When viscosity high and the contact area large, the torque is high, on the contrary, if viscosity low and the contact area small, the torque is low.the damper can work under temperature 30℃, + 110℃. We can adjust the torque according to customer application and also can custom damper according to customer request, customize damper size and torque.


How to use the damper in toilet seat.
This damper can fit a in one hinge

How to confirm the torque.


Toilet seat
  

How to select damper torque.
Torque =Lx1/2xeightx9.8
Seat length is 42cm
Weight is 0.8kg
Cover length is 43 cm weight is 1.0kg
Seat need damper torque is 1.65Nm so it can select 1.5Nm torque damper
Seat need damper torque is 2.1Nm so it can use 2.0Nm torque damper

Customer can give us size of length and weight, and dropping time,we will make test equipment and send customer damper
