The automation upgrading and transformation of auto parts processing enterprises in Dalian will be successful and get twice the result with half the effort. Automatic production line has greater flexibility and can get used to the needs of multiple kinds of production; Under the condition that assembly line production cannot be selected, arranging production line is a more advanced form of production arrangement.

In this situation, the establishment of new energy vehicles and key parts industry bases across the country has been carried out in an all-round way, and the domestic investment in new energy vehicles and key parts will continue to increase in the future. The process of automatic operation or control according to the specified procedures or instructions. The goal is "stable, accurate and fast". Automation technology is widely used in industry, agriculture, military, scientific research, transportation, commerce, medical treatment, service and family.

The adoption of automatic production line can not only liberate people from heavy physical labor, some mental labor and bad and dangerous working environment, but also expand human organ function, improve labor productivity and enhance human ability to understand and transform the world. Since then, colleges and universities have expanded their enrollment in this industry.

Many schools have set up this major. Then in the new century, with the development of electronic computer, digital automatic technology, network technology, automatic control and process assembly, the machining and manufacturing industry is gradually invaded by other majors. Generally, it is processed at normal temperature without causing chemical or phase changes of the workpiece, which is called cold processing. Generally, processing above or below normal temperature will cause chemical or phase changes of the workpiece, which is called hot processing. Cold working can be divided into cutting and pressure machining according to the difference of machining methods.
