Do you know how is the tempered glass film made? 1. Open.  Cut a large piece of glass into small pieces. 2. The cutting.  The rectangular small size glass is processed through the first cutting process, and then the glass material is cut into the shape suitable for the phone model by CNC engraving machine. The glass products that cannot be processed by the general process such as punching and opening steps are required.  The difference between the use of large fine carving machine and the use of general fine carving machine lies in the hole position of the glass film and the edge of the glass film can not be seen with the naked eye. 3. Sweeping smooth grinding: fine finishing.  This process is processed on the toughened film by sweeping machine, which can effectively remove the scratches on the surface of the toughened film and increase the radian and brightness of the edge of the toughened film, so as to achieve smooth, beautiful and durable. 4. Toughened.  Generally, the semi-finished glass film is put into the tempering furnace of about 420 degrees for 4 hours of tempering, to ensure that the glass film even if broken, will not harm the human body. 5. Ultrasonic cleaning.  Need to put the glass into the ultrasonic cleaning agent to clean. 6. Oil injection: determine the effect of oil pollution prevention.  The method is to add a layer of anti-fingerprint oil on the surface of the tempered glass film, and this layer of anti-fingerprint oil coating can also ensure that the surface of the tempered film has stains can be easily removed. 7. Joint.  On the side where the glass film is in contact with the phone, a layer of epoxy AB glue is needed to attach it to the phone screen. 8. Defoaming: deep treatment after gluing. 9. Detection.  Inspect and package the products that have been processed and meet the requirements.
