Reasons for Cracks in the Car Dashboard Glass Cover?
2 Answers
Car dashboard glass cover cracking is related to the material of the dashboard. Here is the relevant information: 1. Car dashboard: Provides the driver with various parameter information about the car's operation, such as speed, mileage, RPM, fuel level, water temperature, as well as the current status of the vehicle and maintenance reminders. It is the most direct way for the driver to determine whether the vehicle is functioning normally. 2. Material: The dashboard panel is made of PMMA material, which is currently the best polymer transparent material with a light transmittance of 92%. Almost all vehicle dashboards we see on the market today are made of PMMA material.
I've been driving for over twenty years and have also encountered situations where the dashboard glass cover cracked. The main reasons are accidental impacts, such as dropping a phone or keys on it when placing items, causing fine cracks on the surface. Additionally, large temperature fluctuations, like extreme heat from summer sun exposure or freezing winter temperatures, can cause the material to expand and contract, leading to cracks. Aging is another factor, as plastic becomes brittle over time. Sometimes, improper cleaning with strong sprays or hard brushes can also cause scratches. I think it's important to avoid piling clutter on the dashboard and try to park in shaded areas. Once cracked, it can affect the readability and safety of the gauges, so it's best to get a new cover replaced at a repair shop and not take it lightly.
