How to choose door hinges? What are the key points for door hinges? Door hinges are materials that we often use in our daily life. Many consumers don't know what to do when choosing door hinges. So in order to let consumers have a better understanding, how to choose door hinges? What are the key points for door hinges?
1. How to choose the door hinge
1. Surface: Check whether the surface material of the product is flat. If you see scratches and deformation, it is produced with waste (scrap). The ugly appearance of this kind of door hinge makes your furniture lack grade. Surface treatment: Most door hinges are nickel-plated, but now because it is very economical and cost-effective, only a thin layer of nickel is plated. The real door hinge should be plated with a layer of acid copper before the nickel layer to prevent rust.
Tips: I will teach you a way to distinguish whether there is plating: if you don’t object, you can use an artist to draw a knife to see if you can see the yellow copper layer. Another more intuitive way is to look at the general door hinge inside the door hinge cup. The cup is recessed and this is also the place where electroplating is difficult. If the inside of the cup shows the same black water level or the iron color can be seen, the plating layer is very thin and there is no copper plating. If the color and brightness of the cup is similar to other parts, then the electroplating passes. Is it very simple?
2. Switching performance: Everyone knows that the key of the door hinge is to play a switch role, so the key to this point is the outer spring, inner spring and rivet assembly of the door hinge. The outer spring is a leaf spring and the inner spring is a spring bar that has to undergo a certain heat treatment. Too hard and easy to break. Too soft to close the door without strength.
Tips: When buying door hinges (except hydraulic hinges), close the door hinges by hand. Is the sound of the door hinge closing clear? Please listen carefully. If it is a dull closing sound, it means that the spring is not strong enough and the thickness of the material is problematic. Is the hinge cup loose? If it is loose, it proves that the rivets are not tightly riveted and easy to fall off. Close it several times to see if the indentation in the cup is obvious. If it is obvious that there is a problem with the thickness of the cup material, it is easy to burst the cup.
3. Screws: Generally, the door hinge comes with two screws, both of which are adjustment screws, up and down adjustment screws, front and rear adjustment screws. already.
Tips: Use a screwdriver to adjust the up and down adjustment screws three to four times, then remove the screws to see if the teeth of the door hinge arm are damaged, because the door hinge arm is made of iron material, so hard and easy to wear without screws There are also cases where the thread is easy to slip or cannot be screwed if the precision is not enough when tapping in the factory. The front and rear adjustment screws are also tested.
Second, the cabinet door hinge installation size
1. Side panel of the door cover: the diameter of the door hinge hole of the door panel is 35*13mm, and the distance from the side is 22.5. The diameter of the door hinge hole is 5*12mm, and the distance from the door hinge point is 5.5mm;
2. Parallel to the door side: the diameter of the hinge hole of the door panel is 35*13mm, and the distance from the side is 22.5mm. X=thickness of the door panel; Y=drop between the door panel and the side panel) The technical requirements of each company are not much different. Many of these technical requirements can refer to the details of the hardware labels in "Hettis Technology and Application", which is useful for designers.
