Guan Jian, the hinge, dark hinge furniture, because the hinge in the life of the average day of a day more than 10 times, so a hinge depends on the quality of your good or bad, the choice of the hinge hardware also need to. Basically can be distinguished from the following aspects of the good or bad.
1, look at the surface: surface material is formed, as seen by row shape, it is waste (scrap) produced, the hinge makes you look ugly, no class furniture. Surface: most hinges are nickel, and now JS is due to hold down costs, only a thin layer of nickel plating is the hinge should be coated with a layer of acid copper nickel layer, good anti rust, tips: to teach you a method: JS does not distinguish whether some object instances can be used to draw force of art knife, see if see yellow copper layer, and a method is to see the general hinge hinge cup inside, go, here is the most difficult place in the cup with electroplating, black water or see iron, proof of plating layer is very thin, and not in the cup with the other color brightness a place near then pass.
