Hydraulic performance: Everyone knows that the hinge key is a switch, so this is very important. Guan Jian takes the damper of the hydraulic hinge and the rivet assembly. The damper mainly depends on whether there is noise when opening and closing. If there is noise, it is a low-quality product. It also depends on whether the round speed is uniform. Is the hinge cup loose? If there is looseness, it proves that the rivets are not tightly riveted and are easy to fall off. Close and close several times to see the indentation in the cup is not obvious. If it is obvious, it proves that there is a problem with the thickness of the cup material and it is easy to "pop the cup". 3. Screws: Generally, hinges come with two screws, which are all adjustment screws, up and down adjustment screws, front and rear adjustment screws.
