As a commonly used accessory product in furniture, the quality of slide rails directly affects the quality of furniture. For mainstream slide rails, the accuracy of plastic pepper balls used directly affects the smoothness of slide rails, while the quality of POM plastic pepper balls used for slide rails varies greatly due to the differences in materials and manufacturing processes of different manufacturers.

The quality of plastic pepper balls on slide rails depends on two aspects:

In order to reduce the cost, some plastic pepper ball manufacturers use the market nozzle material to make the plastic pepper ball for the slide rail, which is not hard enough, and there are other kinds of plastic materials doped in the nozzle material, which causes the plastic pepper ball for the slide rail to crack and break, so the plastic pepper ball used for the slide rail should be made by regular manufacturers.

The precision of plastic pepper balls on the slide rail is a problem. Some plastic ball manufacturers produce plastic pepper balls with small blank size due to poor mold manufacturing. Coupled with the technical problems of post-grinding processing, the tolerance of plastic pepper balls is very large. Such plastic pepper balls will cause the slide rail to be unsmooth or even stuck, which will seriously lead to the damage of the slide rail.
