We are a door hinge manufacturer. We believe that the quality of door hinges can be distinguished from the following three aspects: 1. Surface: Check whether the surface material of the product is flat or not. If scratches and deformation are seen, it is produced with scrap (offcuts). Come out, this kind of hinge looks ugly, making your furniture without grade. 2. Hydraulic performance: Everyone knows that the hinge 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 rivet is not tightly riveted and is 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 adjustment screws, up and down adjustment screws, front and rear adjustment screws. Some new hinges also have left and right adjustment screws, which is the so-called three-dimensional adjustment hinge, usually with two adjustment screws. That's enough. Tips, use a screwdriver to adjust the upper and lower adjustment screws three to four times with a little strength, and then remove the screws to see if the teeth of the hinge arm are damaged, because the hinge arm is formed of iron material and is not as hard as the screw , It is easy to wear, and if the precision is not enough when the factory is tapping, it is easy to slip or cannot be screwed. The front and rear adjustment screws are also tested.
