How we make car glass windows
Have you ever sat in a car (maybe at the driving school – Trafikkskole Horten?) and wondered what would a car loook like if it didn’t have those side windows? A wreck, maybe. These car glass windows not only protect you from an injury but also give your car an enchanting look. But have you ever thought that how are they made? Do they contain anything other than simple glass? Therefore, considering the importance of these car glass windows, in this article, we are going to cover how these car glass windows are made. Without further ado, let’s get straight into it.
- Mixing of Raw Materials:
These car glass windows don’t make out of the blue. It’s a critical step by step process. The first step in this regard is the mixing of raw materials such as limestone, dolomite, and sand. Dolomite is mainly added to equipoise the chemical reactions. In addition to dolomite, soda ash is also a part of this process which is added to minimize the melting temperature. To aid the melting process, a broken glass or a colored glass is added before cutting it into the regarding shape.
- Cutting off the Car Glass Window:
After perfectly mixing up the essential raw materials, the class is cut by a tungsten wheel which controlled by a computer. This wheel cuts the glass into the required shape of the car glass window. Moreover, a flame is thrown upon this certain car glass window which provides a thermal stress to crash it along the edges giving it its required shape.
- Strengthening the Car Glass Window:
After the cutting of the car glass window in a fine and required shape. This car glass window is subjected to strengthening. It’s strengthened when it is subjected to a very high temperature of about six hundred and 30 degrees Celsius followed by a rapid cooling of the glass. This creates a surface compressive stress in the glass making it stronger and tougher. This process is significant for the making of car glass window. Even if this glass is broken down into a million tiny pieces, it won’t cause any harmful injury.
- Lamination of PV:
This lamination is done to provide extra safety to the car glass windows. A layer of PV or polyvinyl butyral gets sandwiched with the glass on the inner side. This material is very stretchable. Hence, even if you (God forbid) goes through an accident, this material will refrain you from getting out of the car. However, now cars have airbags and seatbelts, so this is not very important now. But car glass windows are still laminated as it keeps the person safe.
- Windscreen Lamination:
This car glass window has a different lamination than other car glass windows. Its lamination is slightly thinner as compared to other car glass windows. This car glass window is laminated with a thin plastic layer sandwiched between two glass layers. These two glass layers consist of an outer an inner layer with one being slightly thicker than the other. This is done to make the curvature of the glass perfect. By a SAG bending process, these glass layers are subjected to the bending at six hundred degrees Celsius temperature. These two glass layers get molded. Afterward, the plastic layer is added between the two glass layers. Then this sandwich is subjected to a high-pressure boiler for one and a half hour before going to get its quality checked.
- Check for Quality:
After the car glass windows are made, they are subjected to high-profile quality checking under special lights to clearly analyze the quality of the car glass windows before locking it into its specific car.
