1. Production process of slide rail

The most direct way to distinguish the appearance is to look at the production process. Generally, small factories will choose inferior materials due to competition, and at the same time, the mold and production level are relatively lacking, and the hidden damping slides of powerful manufacturers will use environmentally friendly steel. Its hardness will increase the load-bearing of the slide rail, and at the same time, it is not easy to rust, and the production process is mature and the appearance is good.

2. Pull out strength of slide rail

Push and pull the hidden damping slide rail by hand to see if it needs to be pulled out very hard. Many immature manufacturers are afraid that the slide rail will not have enough force when the drawer is closed, and increase the strength of the spring, but they cannot handle it. The lightness when pulling out is so strong that it is immature.

3. Slide rail closing time

Push and pull the hidden damping slide rail by hand, and it is most appropriate to close the slide rail for about 1.2 seconds from the moment when the slide rail produces the damping effect. It is possible that the lower drawer cannot be tightly closed after long-term use. Generally speaking, hydraulic shock absorbers for damping slides are easier to grasp the closing time, while pneumatic shock absorbers are more difficult to control.

4. Whether the slide rail swings

The slide rail mounted on the drawer should not sway too much. If it is too large, it will generally give people a bad feeling. What's more deadly is that the damping rod buffer of the hidden damping slide rail may not be brought out of the way. Cause this high-end feature to disappear.

5. Slide durability test

This is the most direct and important indicator of the quality of the slide rail, but not everyone has such a test method, allowing the slide rail to complete 50,000 runs under a load of 25 kg without damage. Or whether to obtain a certificate from an inspection agency such as SGS would be a good choice. After all, if the drawer is opened and closed 50,000 times by hand, no one will have such patience.

In general, the hidden damping slide is a high-tech product. It does not have a certain technical strength and is not enough to support its effect and durability. The blind pursuit of cheap prices may lead to the upgrading and brand promotion of furniture products. Win or lose.

Hidden track detailed classification:
According to the pulling stroke, it can be divided into two rails for the bottom and three rails for the bottom.
