When buying a hinge, don't just focus on the price, but compare the quality_Hinge Knowledge

Chinese furniture hinge manufacturing is a vast industry, with numerous manufacturers, both large and small. However, an astounding 99.9% of hidden hinge manufacturers are concentrated in Guangdong. This province has become the epicenter of spring hinge production and is divided into various main concentrated areas.

Customers often find themselves perplexed when it comes to the pricing of hidden hinges. At trade fairs or while searching online, buyers are faced with a wide range of prices. For instance, a two-stage force hinge with similar weight and appearance can vary in price from 60 or 70 cents to 1.45 yuan. The difference in pricing can even be doubled. It becomes nearly impossible to differentiate the quality and price solely based on appearance and weight. In such cases, it is advisable for hinge buyers, especially those with large quantities and in need of better quality, to directly visit hinge manufacturers. By doing so, they can learn about the production process, quality management system, and production scale of the manufacturers.

1. Hinge Production Process:

Some hinge manufacturers adopt fully automatic production processes, covering everything from the base to the bridge body and associated links. This level of automation ensures higher quality. Manufacturers who invest nearly 200,000 yuan in fully automatic molds usually have a certain scale to support such costs and talent reserves. These manufacturers have stringent inspection standards and ensure that subpar hinges do not enter the market. Conversely, some other hinge manufacturers only assemble hinges without checking their feasibility, allowing low-quality products to flood the market. This difference in production processes contributes to the varying prices of hinges.

2. Hinge Production Materials:

Hinges usually adopt Q195 as the material for automatic production. Expert examination can easily identify fully automatic production parts as they possess shear interfaces. However, some hinge manufacturers utilize leftover materials, such as rolled oil drums or electrolytic plates of lower quality, to reduce production costs. In contrast, fully automatic production employs first-hand materials from reputable manufacturers, ensuring consistency in material thickness. This difference in materials also contributes to price disparities.

3. Hinge Surface Treatment:

The price of a hinge can greatly depend on the quality of its surface treatment. Typically, high-quality hinge treatment involves copper plating followed by nickel plating. Nevertheless, the efficacy of electroplating is contingent upon the expertise of the manufacturer. In the case of inferior materials, direct nickel plating might be a preferred solution. It is not uncommon for new hinges from subpar manufacturers to exhibit rust even before opening the package.

4. Quality of Hinge Parts:

The heat treatment of hinge accessories such as barbecued pork, chain rods, and screws significantly affects the hinge's overall quality. It is difficult for customers to discern whether these accessories have been heat treated. The ability to withstand more than 50,000 opening and closing tests is often contingent upon proper heat treatment. In contrast, hinges with lower prices tend to encounter issues within 8,000 opening and closing cycles. The degree of heat treatment is not easily discernible for new hinge manufacturers, further contributing to pricing differences.
