Selection points for door hinges

Door hinges open and close more than 10 times a day on average in everyone's life, so the quality of a hinge depends on the performance of your furniture, and you also need to pay great attention to choosing the hinge hardware in your home.

The quality of the door hinge can be distinguished from the following three aspects: 

Surface: Check whether the surface material of the product is flat. If scratches and deformations are seen, it is produced from waste (leftover material). This kind of hinge looks ugly and makes Your furniture is of no class.

Hydraulic performance: Everyone knows that the hinge key is the function of a switch, so this is very important. The key is taken from 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 an inferior product, and whether the round speed is uniform. Is the hinge cup loose? If there is looseness, it means that the rivet is not tightly riveted and is easy to fall off. Close and close a few times to see if the indentation in the cup is obvious. If it is obvious, it proves that there is a problem with the thickness of the cup material, and it is easy to "explode the cup".

Screws: Generally, the hinge comes with two screws, all of which are adjustment screws, up and down adjustment screws, front and rear adjustment screws, and some new hinges also have left and right adjustment screws, which is now the so-called three-dimensional adjustment hinge, generally with two adjustment screws The work place is enough. Tips, use a screwdriver to adjust the upper and lower adjustment screws three to four times with a little force, then remove the screws to see if the teeth of the hinge arm are damaged, because the hinge arm is formed of iron material, not as hard as the screw , It is easy to wear and tear, and if the precision of the factory tapping is not enough, it is easy to slip the thread, or it cannot be screwed. The front and rear adjustment screws are also tested.
