How Is A Windshield/Windscreen Made

Cars, bikes, buses and trains are some things that all of us have seen. When you are riding these vehicles then you must have thought about the efforts that are put into the vehicles to make them safe. Each and every vehicle has some integral components that make them safer. One of the most important safety components that is present in almost every vehicle is a windscreen or windshield. A windscreen supports the roof structure and also protects the passengers from wind, dust and other objects that might be in the air.

Sometimes you might wonder that how windshields are made, they are manufactured by using float methods and tempered heat bonding. Both of these processes make the windscreen strong and secure. Here you will learn some things about how windscreens are made.

Windscreens were used in vehicles since a very long time, but it was until the early 1900s when windscreens were made using safety glass is order to increase driver protection. However, these windscreens shattered very easily, whenever the vehicle made an impact these windscreens would shatter and would cause a lot of injuries. To overcome this problem manufacturers tried a new system in mid 1900s and called it laminated windshields, it is the system that is used till this day.

The windscreens that are used today comprise of two laminated sheets of glass, in the center of these sheets there is plastic coating that holds the whole thing together. This makes the glass more strong and does not let it break easily after a minor impact. However, when the glass does break the pieces stick to the plastic coating and do not scatter over the passengers, this makes the glass safer.

Manufacturing Process

The manufacturing process of windscreens and windshields is pretty much the same as normal glass. Raw materials like silica, op4_3312_web1soda ash and limestone are heated at about 1700oC until they become liquid. The molten mixture is then spread on molten metal like till which allows the glass to float over it, the molten mixture then spreads out and becomes flat. After the removal of impurities the molten glass enters a special furnace where the temperature is slowly reduced. If the glass is cooled to quickly then the strength is effected, therefore this step needs its time.

After the glass is cooled then it is cut into a shape using a diamond blade, the glass is then placed on a curved mold that is designed according to the vehicle for which the windscreen is to be used. It is then heated until it perfectly fits the mold. The glass is then tempered using heat induced strengthening tactics. With the help of this tactic the glass does not shatter easily and when it does it shatters into very small pieces which are harmless.

These were a few things that you should know about the manufacturing process of windscreens. These screens are perhaps one of the most important components of any vehicles therefore their manufacturing must be done with great care.

Hey there! At least for one time in your whole life you would have thought about the glass present everywhere around you. You would wonder how it is made and then cut in the desired shapes to fit in different requirements. Or even get inspired numerous building that have major portions of glass in them that are a great site to look; the cuts they are exhibiting, or the color they are reflecting, or different shades present in them from different angles; these all sometimes make people wonder about the fact that how these are made, and so on.
