Auto parts processing plays an important role in the whole automobile production. It covers a series of steps from raw material processing to parts maintenance, and is an indispensable part of the automotive industry. Firstly, auto parts processing can ensure the quality and performance of auto parts, thus ensuring the safety and reliability of automobiles. For example, in the implementation of the National VI emission standards, automotive front-end processing and exhaust treatment will usher in a larger development space, which requires technical support for automotive parts processing. Secondly, auto parts processing can improve production efficiency and reduce production costs. For example, the rapid development of new energy vehicles and autonomous driving will also promote the rapid development of related parts, which requires the technical support of auto parts processing. Finally, auto parts processing can also promote technological innovation and development of the automotive industry. For example, automotive thermal management system energy consumption accounted for about 30% of the vehicle, is a key factor affecting the range, which requires technical support for automotive parts processing. Therefore, auto parts processing has an important position in automobile production, which can not only ensure the safety and reliability of automobiles, but also improve production efficiency, reduce production costs, and promote the technological innovation and development of the automobile industry.
