Technical Field
The invention belongs to the technical field of automobile equipment, and particularly relates to a method for producing and processing an automobile precision plastic lamp housing.
Background
In 1879, the German Engineer, Call Bentz, succeeded in first testing a two-stroke test engine. In 1883 and 10 months, he created "Bentz corporation and Rhein gas Engine plant", in 1885, he made the first Bentz patent motor vehicle in Mannheim, which was a three-wheeled vehicle employing a two-stroke, single-cylinder, 0.9 horsepower, gasoline engine, which was equipped with some of the basic features of modern vehicles, such as spark ignition, water-cooled circulation, steel tube frames, leaf spring suspensions, rear wheel drive front wheel steering and brake handlebars, etc. On 29 months of 1886, the german engineer, karl bentz, patented his motor vehicle. In the same year, 11 months, the three-wheeled motor vehicle of Carl Benz acquired Deutsche patent rights. This is the first modern car in the world to be recognized. For the reasons mentioned above, people generally consider the year 1886 as the original year of the automobile, and some scholars consider the year 1885 when the first three-wheeled automobile was manufactured by Karl Benz as the birth year of the automobile.
The automobile comprises a plurality of structures, wherein the structures comprise an automobile lamp shell, the earlier lamp shell is made of glass materials, the lamp shell made of glass materials is high in transparency, but fragile and high in weight, so that various plastic products are used for replacing the lamp shell, and most of the existing automobile lamp shells are low in transparency.
