Problems solved by technology

[0004] Automotive interior materials generally have a matte requirement, which is beneficial to reduce the driver's visual fatigue, thereby improving driving safety. However, the surface gloss of general interior materials is high, and it needs to be sprayed with matte paint and other secondary coatings. Processing to achieve matte and beautiful effects not only increases the cost but also affects the environment
