Integrated die-casting process is increasingly widely applied in the manufacturing of new energy vehicles due to its characteristics such as simplification, high efficiency, lightweight and high strength. However, because of short evolution time, immature and inconsistent design of process routes among various enterprises, there are significant differences both in cost and efficiency. This paper compares the advantages and disadvantages of various process routes and suggests adopting aluminum liquid direct supply scheme, automatic online measurement combined with automatic deburring, and using tapping instead of thread sleeve process as much as possible if conditions permit, which can significantly reduce production costs and improve production efficiency. However, this scheme still has many shortcomings in wide application. By exploring the advantages and disadvantages of process routes used in key processes of various enterprises, more efficient, more economic, high quality and stable process route are summarized deeply.
