In decoration, it is very significant to choose the proper hydraulic hinge. If you fail to choose the hinge properly, you will likely encounter problems such as the cabinet door is difficult to close, opening and closing are not smooth, and even produce a noise. So you should not be negligent to choose the hinges. In fact, when you choose hydraulic hinges, you should pay attention to the following main points:
Hinge Material, Weight And Appearance
Material and Weight
Most individuals think that the heavier the hydraulic hinge, the better, but not exactly. Weight is only a point of reference, and the material quality is what is utilized to determine the quality. If two hinges of the same material are being compared, the heavier and denser they are, the better quality. But if the hinges are made of different materials, they must be compared based on material physical properties. Good material hinges are more capable of withstanding weight and cannot easily deform.
Common Materials
Common hinge materials on the market include 201 stainless steel, 304 stainless steel and cold rolled steel.
- 201 stainless steel: harder, but poor corrosion resistance, easy to rust.
- 304 stainless steel: softer, strong rust resistance, but higher price.
- Cold rolled steel: smooth surface, light texture, high strength, comprehensive performance is often better than 201 and 304 stainless steel.
It should be noted that although some hinges are advertised as 304 stainless steel, their outer shell may be made of 201 stainless steel, and only the internal laminations and pins are 304. This kind of hinge is prone to loosening, sagging and other problems after long-term use, affecting the use of the cabinet door.
Appearance
When choosing a hinge, appearance is also an important reference point. High-quality hinges are usually exquisitely made, with no deep scratches on the surface, smooth lines, and well-processed details. Good hinge manufacturers also put more effort in these aspects, and the appearance of their products is often more competitive.
Number of Bearings And Laminations
Load-Bearing Capacity
Many people think that the more laminations there are, the stronger the hinge is, but this is not actually the case. Generally speaking, 3 to 5 laminations are enough to meet the load-bearing requirements of the cabinet door. The real load-bearing capacity comes from the iron pins and bearings of the hinge.
Some hinges on the market seem to have a lot of laminations, even 7 to 8. Although they look quite “solid”, they actually require higher processing accuracy. If the accuracy is not achieved, the hinge will easily have problems after thousands of openings and closings, resulting in unsmooth opening and closing, and even noise.
Hinge Cylinder Depth And Rust Resistance
The depth of the hinge cylinder: The depth of the cylinder determines the adjustment range of the hinge. The traditional hydraulic hinge cylinder is deeper and the adjustment range is smaller. When closing the door, if there is a sense of jamming or the opening and closing speed is too different, there may be a problem with the cylinder.
Anti-rust performance: Anti-rust performance is a very important point in hinge selection. Generally speaking, hinges that can pass the 48-hour salt spray test have stronger anti-rust ability. When purchasing, you still have to look at the actual anti-rust test data, and don’t be confused by the so-called “tested 200,000 times” packaging propaganda. Many hinges have not actually been tested in this way, and may lose their buffering function after only a few hundred times.
Fatigue test: Due to the manufacturing level of most hinge manufacturers, hinges that can pass 30,000 opening and closing fatigue tests are considered relatively good. Some hinges claim to be able to open and close 500,000 times or even 1 million times. In fact, these numbers may not be true. Consumers should avoid being misled by false propaganda when choosing.
In general, when choosing hydraulic hinges, you must take into account the material, quality of bearings and laminations, cylinder shape, and anti-rust resistance. It’s better to choose a famous brand to ensure the quality and service life of hinges. After all, choosing appropriate hinges during decorating can make the cabinet doors be smoother and more comfortable to use.
