How Auto Glass Is Made
The Tempering Process
The tempering process begins by cutting raw glass to an exact size and shape, then smoothing the sharp edges. Side and rear windows undergo a silk screening process. In addition, the electric circuit for heated rear windows is screened on with a silver ceramic paste that bonds to the glass as it bakes. The bending process follows and the glass is then transported through a furnace with temperatures as high as 1500 degrees Fahrenheit. Curved rolls, presses or bending rings are used to shape the hot glass and then pressurized air-cools it quickly. The window looks like ordinary glass but it is much stronger. Nevertheless, if tempered glass does break, it disintegrates into small fragments with rounded edges.
Residents of Parker, Palo Verde, Morristown, and Circle City: The tempering process makes the auto glass in your vehicle stronger and safer, protecting you and your family in the event of a head on or rollover accident.
The Laminating Process
The windshield laminating process begins when two pieces of glass are cut to an exact pattern. Then the edges are smoothed and the cut glass is washed, dried and matched together. A black paint border is silk screened on the inside surface and the matched pieces of glass are then placed on bending irons and moved through a furnace called a Lehr. Heat softens the glass allowing it to conform to the shape of the bending irons. After the glass cools, it travels into a climate controlled dust free room where it is sandwiched together with a strong vinyl interlayer. At this point, the heat and pressure of an autoclave permanently bond the glass and vinyl into a single transparent windshield.
