How to choose high quality hinges?
1 surface
Material is the most critical factor affecting a hinge. The hinge punched out of high-quality steel is flat and smooth, with delicate hand feeling, thick and even, and soft color. But the inferior steel, obviously can see the surface rough, uneven, even with impurities.
Electroplating
Hinge cup is the most difficult place to electroplate. If the hinge cup shows black water stains or iron-like stains, it proves that the electroplating layer is very thin and there is no copper plating. If the brightness of color in hinge cup is close to that of other parts, electroplating will be carried out.
3 rivet device
Hinges and rivets of good quality are of fine workmanship and have relatively large diameters. Only in this way can we bear a door panel of large enough size. So as to ensure the service life of the hinge.
4 screws
General hinge comes with two screws, which belong to adjusting screws, upper and lower adjusting screws, front and rear adjusting screws. The new hinge also has left and right adjusting screws, such as AOSITE three-dimensional adjusting hinge.
