Car glass is an essential component of any vehicle, providing safety and protection for the driver and passengers. But what is car glass made of? In this article, we'll explore the elements of car glass, the different types of glass used in vehicles, and the manufacturing process. The windshields of cars are made of a specialized form of glass designed specifically for windshields. This glass is composed of silica, fine sand, soda ash, dolomite, waste glass, limestone, and small amounts of potassium oxide and aluminum oxide.
Rear glass, also known as rear window glass or rear windshield, is made of tempered glass, also known as safety glass. When broken, it breaks into small round pieces, unlike the front windshield which is made of laminated glass. Laminated glass consists of two pieces of glass with a thin layer of vinyl in between them. This creates a thicker and stronger window that is more difficult to break.
Safety glass is used in all automotive glass to reduce the likelihood of injury should it break. Windshields are manufactured through a lamination process that involves two pieces of float glass with a thin layer of vinyl between them. Nearly all windshields in North America are made from laminated glass. When a small object hits a piece of safety glass, usually only the outer layer breaks.
Silica makes up 65-70% of windshield glass, while soda ash lowers the melting point of the mixture and dolomite makes it easier to work with. Limestone increases the efficiency of the glass and gives it a good finish while also making it more durable. The tempering process further strengthens the glass by rapidly heating it and then blasting it with cold air. Companies such as AGC Glass Company North America, Guardian Industries, PGW Glass, Pilkington North America and Vitro produce tempered automotive glass that meets original safety and quality specifications.When laminated glass breaks, it breaks into small pieces instead of large fragments which makes it safer.
Molten plastic is then injected into the mold to form a plastic frame around the glass so that it can be shipped to car or glass manufacturers.For windshield replacement, you have the option of selecting a replacement made by an Original Equipment Manufacturer (OEM) or aftermarket manufacturers.When it comes to vehicle safety, people often forget the importance of suitable automotive glass. Automotive glass must meet original safety and quality specifications in order to provide maximum protection for drivers and passengers.
