EPC is a kind of foundry techniques nearly without machining allowance and can mold with precision, which is easy to achieve the purpose of cleanness, mass production and provides abundant freedom to design complex structures of castings. The mobile phase front of molten metal is the product of thermolysis evanescent mode (gas or liquid), which can react with molten metal and influence the quality of molten metal. If in the process of molding, the thermolysis products can not be removed, it will cause defects, such as air hole, cockle and carbonization, etc. so the technicians must grasp the principle of EPC casting mould, design casting system correctly and make rational technique scheme. Though cost of integrating casting is very low, it is better to mass produce in order to gain optimal economical benefit
