[0002] With the development of the national economy, the automobile industry has become a pillar industry of the country. The current rapid development of the automobile industry has put forward higher and higher requirements for automobile lighting. Automobile headlights are important components for safe driving of vehicles. Vehicles and road pedestrians provide lighting, so countries all over the world have strict requirements for automotive lighting. At present, manufacturers use traditional methods to produce aspheric lenses, mainly by grinding, which is time-consuming and laborious. It also pollutes the environment and is very difficult to process. , is only suitable for small batch production. Although there are aspheric lenses for automobile headlights produced by other methods in foreign countries, the process is complicated and the cost is high. The country needs to rely on imports, and it needs to spend a lot of foreign exchange every year.
