1. Check the batch number

Shangyin Products can check the sales channel of this batch of guide rail sliders through the production batch number, so the production batch number of each batch is different. The five are constantly changing.

The production batch number of the silver guide rail slider is laser-engraved and has anti-counterfeiting function

Genuine silver guide rail slider: the text needs to be seen clearly on the backlight surface, and the steel seal and font are clear Full and strong three-dimensional effect

Fake silver guide rail: no steel seal and anti-counterfeiting label, or it can be seen clearly when looking directly from the front

2. Look at the trademark

Genuine silvering guide rail: The LOGO has smooth lines and is there a trademark?

Authentic product Silver guide rail: The chamfer is a standard 45-degree chamfer

Fake silver guide rail: The chamfer is an arc angle

This detail is the key to identifying this fake silver guide rail incident Point

The accuracy of fake guide rails cannot meet the requirements after installation and debugging, but the accuracy can be adjusted when no preload force is applied. When the pretightening torque exceeds 80N·m, the guide rail is biased due to the arc angle, resulting in large linear runout

6. Measure the hardness

Genuine silver guide rail: Use a blade to scratch Damage to the guide rail, the silver-plated guide rail has high hardness and only slight scratch marks

Fake silver-plated guide rail: The scratch mark on the guide rail is very deep, and there are many scars on the guide rail during rapid transportation
