How to test the performance issues of installing hinges

One side of the two parts connected to the shaft should be fixed to the door and window. When installing, please ensure that the hinges on the same fan are on the same vertical line to prevent doors and windows from bouncing. Turn off the sound of the spring and release the test cup.

Hinges are the function of switches, so this is very important. The outer and inner springs are taken from the hinge and assembled with rivets. It is clear to hear the sound of the hinge. If the sound is boring, it indicates that the spring is not strong enough and there is also an issue with the thickness of the material. If the hinge cup is loose, if it is loose and the rivet is not tight, it is easy to fall off.
