The production of AUTO GLASS is to heat the glass to close to the softening temperature in the heating furnace, and then quickly send the glass into the wind grids with different cooling intensities to cool the glass unevenly, so that the main viewing area of the glass is different from the surrounding area. Stress, generally the glass produced in this way is area tempered glass.

The surrounding area is in the strong wind position of the air grille, so it needs to be fully tempered. The degree of fragmentation in this position is good and the tempering strength is high. The main viewing area is in a weak and cold position of the air grille, with large fragments and low tempering strength.
AUTO GLASS is an indispensable part of the car body accessories, mainly for protection. AUTO GLASS mainly has the following three categories: laminated glass, tempered glass and area tempered glass, which can withstand strong impact. AUTO GLASS is divided into four types according to its location: front windshield, side window glass, rear windshield glass and sunroof glass. The front windshield is mandated by the state to be laminated glass, (the front windshield of some cheap agricultural vehicles is still tempered glass or regional tempered glass), the side window glass is tempered glass, and the rear windshield is generally tempered glass with electric heating wire.
