As an important part of furniture such as doors and windows, hinges play an indispensable role in daily life. Its material and quality are directly related to the experience and service life. This paper will start with the basic introduction of hinge, discuss its material selection, and provide some simple and practical quality judgment methods.
I. Introduction of Hinge
Hinge is a mechanical device used to connect two objects and allow them to rotate relatively. In home decoration, the most common application is in doors and windows. According to different installation positions and requirements, hinges are classified in many ways, such as door hinges and cabinet hinges. Different types of hinges have different requirements for materials.
Second, the common materials and characteristics of hinges
1. Stainless steel: It is one of the most commonly used materials in the market at present. Stainless steel has good corrosion resistance and strength, and is suitable for use in various environmental conditions, especially in wet or dusty environments. In addition, stainless steel hinges have a long service life.
2. Copper alloy: Copper alloy is famous for its excellent corrosion resistance and is often used in high-grade products or special requirements. But the price is relatively high.
3. Aluminum alloy: It is light in weight, low in cost and easy to process and shape, so it is also widely used in hinge manufacturing. However, the hardness of pure aluminum itself is not high enough, and it is usually necessary to add other metals to improve its mechanical properties.
4. Iron (surface treatment): It is a good choice for economical products. In order to prevent rust, chromium plating or painting treatment is generally carried out to enhance the anti-corrosion ability.
Third, how to judge the quality of the hinge
Observation appearance: the surface of high-quality hinge is smooth and burr-free, and the color is uniform; And inferior products may have problems such as bubbles and depressions.
Touch detection: pick up the hinge and gently shake it to listen to the sound. A good quality product should make a crisp sound instead of a dull sound, indicating that the internal structure is highly compact.
Check the thickness: the thickness of a single plate can be measured by calipers. Generally speaking, the thicker the material, the better the stability. At the same time, pay attention to check whether the gap between the two plates is uniform.
Actual test: If possible, it is best to personally test the smoothness of opening and closing process and whether there is abnormal sound.
To sum up, the hinge made of reasonable materials and with good technology level can ensure long-term stable operation without problems. In addition to considering the price factor, consumers should also pay attention to the above aspects before making a decision to choose a good product that really suits their needs!
