Automotive glass, is an integeral functional part of the automobile. The windshield not only prevents atrocious weather, it and also ensures driving safety! Therefore, high-quality automobile glass is particularly important to the integretity of the vehicle. The manufacturing processes automotive glass goes through will be classified in following: The first process: Monitor the Quality of Raw Materials A piece of high-quality automotive glass is directly associated with the raw material-float glass. Fuyao Group currently has 11 float glass production lines, each of which is equipped with on-line inspection equipment. This process can inspect most common float glass quality defects, such as bubbles, stones, nodules etc. This ensures the glass quality is monitored before moving to the second process. If the quality standard is not met, the glass will not be able to move to the next process and will be immediately recycled.

The second process: Production Process Control A piece of high-quality automotive glass has to pass many tests and be checked several times during the production process. For example, the glass will be inspected in the deferent stages, including appearance, size and so on. For key projects, the factory will also conduct random inspections. These manual inspections check for obvious defects in appearance, using inspection tools to inspect glass, and testing the stress, resistance and optical properties of glass.

The third process: Performance Test Finished glass needs to pass rigorous laboratory tests before delivery. Mechanical Test: A mechanical test is used to test the properties of the glass under impact. The following experiment is used to simulate what happens when a person makes contact with the front windshield during a violent collision. Glass Meeting Safety Standards:

• When the laminated glass is impacted, the glass and the intermediate film must be bonded to prevent the debris from splintering and harming the driver and potential passengers.
• The glass must be broken when a person hits it, otherwise the person's head will absorb all the impact energy and cause further injuries. Meanwhile, the glass should not be penetrated, preventing secondary damage.
• When tempered glass is broken, the number of fragments in any square of 50mm*50mm should not less than 40 pieces and not more than 400 pieces. If the framents are too large or too small, glass fragments will cause potentially more harm to individuals in the vehicle.

Salt Spray Test: High temperature and humidity in coastal areas is a particular challenge for the service life of metal materials such as pins and mirror brackets on automotive glass. Salt spray test is carried out at 35℃, and high concentration brine (5% sodium chloride brine) solution is used to simulate the extreme environment of high temperature and high humidity to observe the corrosion state of metal parts on automotive glass. Defrost Experiment: In regions where there is frost and freezing in winter, affect driving safety. Defrost testing mainly tests the defrosting function of automotive glass in cold weather. Through the power-on test, the defrosting effects achieved within the specified time can be visually observed. Optical Inspection: Automotive glass requires good optical performance to ensure good visibility for drivers. Optical inspection can judge whether the optical performance is qualified by simulating the deformation of objects outside the window when a car is running. Deformation will cause the circle image to become oval and the straight line to become wavy. The inspection items of automotive glass are far more in depth than those mentioned above, and various inspection methods are continuosly adopted. The ultimate goal of all inspections is to assure quality and contribute to safe driving.

Since 2020, Fuyao Group has upgraded anti-counterfeiting measures and established an anti-counterfeiting traceability management system for genuine auto glass with high-tech means. The anti-counterfeiting traceability code is placed in the transparent pattern next to the trademark through the glass laminating process, which is non-removable. 

Consumers only need to scan the QR code on the glass trademark to enter the Fuyao Glass Anti-counterfeiting Inquiry page, check product information, compatible vehicle models, production origin and other details, and obtain complete traceability from production to circulation to confirm genuine Fuyao glass. The system effectively cracks down on counterfeiting and sales, prevents brand infringement, and protects consumers’ legitimate rights and interests from the source.

No special maintenance is needed. Coated glass adopts vacuum magnetron sputtering technology to evenly coat nano-scale metal film inside the laminated front windshield, and adopts edge sealing technology to stabilize the film performance. No extra maintenance is required during use.

The heat insulation and sun protection functions of coated glass are lifelong. Adopting the heat reflection principle, its performance will not decline with long-term use. As long as the coated glass is not broken, it can serve the vehicle owner until replacing a new car.

No. Fuyao coated glass adopts an additional laser film removal process in production to reserve signal receiving windows for GPS, ETC and other electronic devices, supporting barrier-free signal reception.
