　　a. The alloy composition in molten aluminum deviates from the standard seriously, especially the low Fe content, which will promote the wettability of molten aluminum and die and increase the tendency of mucous membrane;

　　b. The effect of the selected release agent is not good, resulting in the casting can not slide out smoothly;

　　c. The mold demoulding slope is not enough, and the demoulding is not smooth;

　　d. There are many cracks on the surface of the mold, which is too rough and causes the mucous membrane.
