It is normal for new car glass production dates to differ. "Because car glass is typically produced by other factories and then transported to the assembly workshop for assembly, the production dates must vary depending on the batch of glass produced by the car glass factory.". "Glass spare parts will be prepared some time in advance, and there is no guarantee that they will be assembled immediately each time. Therefore, it is normal for glass production dates to differ somewhat from each other.".

Identify whether the car glass has been replaced:

1. Looking at the glass label, in most cases, after the replacement of automotive glass, the label on the new glass will be significantly different from the original glass. Generally, the original glass label not only has the identification of the automobile brand, but also has the identification of the glass brand.

2. According to the production date, under normal circumstances, the production date of the entire vehicle glass is close to the production date of the entire vehicle. If there is a significant difference between the production date of one glass and the other glass, it indicates that the glass has been replaced.

3. Look at the manufacturer. By looking at the manufacturer's code number on the glass, you can see which manufacturer the glass comes from. Generally, automobile manufacturers purchase glass in batches, and do not use too many brands or different origins of the same brand.
