1. Look at the appearance, take a few more sofa hinges to see if the appearance of the hinge is roughly the same. The hinges produced by many poor hinge factories are black here and yellow there. The plating is not stable and the plating layer is thin, so it is easy to rust.
2. Take the iron cup of the hinge and close the hinge slowly like closing the door. Remember to be slow. If you feel that the hinge is very smooth and unimpeded, and even the test is very smooth, then the sofa hinge product is initially qualified. If you find any obstruction or noise in the middle, or even both, you should be careful whether the hinge has quality problems.
3. After the door is installed, press down slightly to see how the hinge is stressed. If it is easy to sink and is serious, you should be careful that the door panel will appear asymmetric in the future.
4. Use professional fatigue tester to test its durability, and use salt spray tester to test its rust resistance. This is not what ordinary consumers can achieve.
5. Use a screwdriver to test the adjustment screws of the hinge and the fastening screws at the end of the hinge to see if it is easy to slip. If it is easy, it is very troublesome to pay attention to the use of such hinge. If it can't be adjusted, it's not stable. It's only a sigh
