The important factors to ensure mold filling involved f ollowing events: rational pouring velocity and static head
permeability of mold shell
melt and mold shell temperatures during pouring
avoidence of gas releas e obstruction from mold shell during pouring
and of discontinuous pouring
quara ntee of steady filling. Shri nkage hole transfer and dispersion were two effective methods to avoid shrinkage hole(porosity) in casting. According to different casting structure
either met hod can be selected.
