Key points for purchasing hinge hinge

1. The materials should be corrosion-resistant and of solid quality

When purchasing hinges, it is necessary to make choices based on the environment and material characteristics. When purchasing, it is also possible to weigh the weight of similar products from different brands, and high-quality products are preferred.

Steel hinges are prone to rusting and are not suitable for general use in damp environments; Copper hinges have corrosion resistance and antibacterial properties, making them suitable for use in bathrooms; Aluminum hinges have lower strength and are generally thicker; Stainless steel material has good decorative and functional properties, making it a popular choice for many families. However, when purchasing, it is important to be careful when merchants use products with surface coatings that are mixed with fish's eyes and pearls.

2. Smooth appearance and good surface treatment

Firstly, check if the surface material of the hinge is flat. If you see scratches or deformation, it indicates that the product is produced from waste; Secondly, carefully observe the surface treatment of the hinge and make a cut to see if a yellow copper layer is visible. Alternatively, look inside the hinge cup. If the cup shows the same black color or iron color, it indicates that the electroplating layer is very thin and not plated with copper. If the brightness of the cup color is close to other parts, the electroplating is qualified. Overall, well-designed hinges have a beautiful appearance, small gaps, and are more reliable to use.

3. Large bearing diameter and thick wall plate

The quality of the flat hinge mainly depends on the quality of the bearings. The larger the diameter of the bearing, the better. The thicker the wall panel, the better. Hold one hinge flat in your hand and let the other slide freely, with a uniform and slow motion.

4. Close and listen to the sound of the spring, loosen the trial hinge cup

The hinge key serves as a switch, so this is very important. The key is taken from the outer and inner springs of the hinge, as well as the assembly of rivets.

Listen to the sound of the hinge closing to see if it is clear and crisp. If the closing sound is dull, it indicates that the spring force is insufficient and there is an issue with the material thickness; Check if the hinge cup is loose. If it is loose, it indicates that the rivet is not tightly riveted and is prone to detachment. Close the cup several times to see if the indentation is obvious. If it is obvious, it indicates that there is an issue with the thickness of the cup material, which can easily "explode" the cup.

5. Test screws, adjust with force

Use a screwdriver to adjust the upper and lower adjustment screws three to four times, then remove the screws and check if the teeth of the hinge arm are damaged.

Due to the fact that the hinge arm is formed from iron material, it is not as hard as screws and is prone to wear and tear; In addition, if the accuracy of the factory tapping is not enough, it is easy to cause slipping or inability to twist.
