When analyzing the case, it is found that when the pouring system design is unreasonable, even if the temperature of pouring liquid metal is high enough, the same casting will appear in high temperature area and low temperature area, shrinkage hole loosening defects in the high temperature area, the foam gasification in the low temperature area is slow and incomplete, and defects such as wrinkled skin, carbon slag, and pores ompatnag la{}} Say sigpot a panagaral ed sayan nagagawa so mangitonton ed sikatayo a mansumaryo ed taloran teorya na "agos na agos, lawak na tela tan negatibon lawak na presyon"{1}.

At the same time of three theory, put forward the disappear die casting must follow the third basic principle: through the regulation of the flow field heat field reasonable distribution, the realization of the casting and solidification or sequential solidification, and minimize the heat loss of the pouring system, make the type cavity metal liquid temperature close to the temperature of the metal liquid in the pouring package. The sequential solidification is the process of liquid metal{1}.
