Where to Check the Production Date of Car Windshields?

[VonHayden]

Car windshield production dates can be found in the lower right corner of the front windshield. Car windshields are essential body accessories that primarily serve a protective function. There are mainly three types of car windshields: laminated glass, tempered glass, and zoned tempered glass. Laminated glass is a glass product made by bonding two or more layers of glass with one or more layers of transparent adhesive material. Tempered glass undergoes a process where low-temperature, high-speed air currents uniformly quench the glass, creating tensile stress inside the glass and compressive stress on the outer surface, resulting in the treated glass product. Zoned tempered glass is heated in a furnace to near its softening temperature, then rapidly transferred to air grids with varying cooling intensities for uneven cooling, creating different stresses in the main viewing area and the peripheral areas, resulting in the treated glass product.
