Abstract：
In view of the disadvantages of the low stability and dimension accuracy of the green sand casting process in the
production of high-quality automobile parts, a casting process of plastic sand shell with shaped metal support was proposed.
The process can not only meet the requirements of producing high quality castings, but also reduce the cost and pollution.
At the same time, through the combination of this process successfully produced high quality, high yield (96%~98%) of
German MAN automobile engine head case. The potential advantages of this process in the field of auto parts preparation
are further verified.
