Is it normal for the production dates of new car windows to be different?

[ODawson]

It is normal for the production dates of new car windows to be different because car glass is produced in batches on assembly lines, resulting in varying production dates. Car windows typically feature letters, numbers, and patterns that represent the car manufacturer, glass brand, production date, and the China 3C mandatory certification mark. Car glass is an essential component of the vehicle body, primarily serving a protective function. There are three main types of car glass: laminated glass, tempered glass, and zoned tempered glass, all of which can withstand strong impacts. Car glass is categorized into four types based on its location: front windshield, side window glass, rear windshield, and sunroof glass.
