摘要：

Aeration filling is a new flask (or moulding chamber) filling method, which has been developed from the shooting/blowing process. As a sand filling stage, aeration filling determines the ultimate quality of mould in a sense, such as integrality and uniformity. If the moulding sand can be filled in every part of the mould cavity, an accurate shape would be replicated after the finial compaction stage, otherwise the mould may have weak regions. This paper focuses on the study of the sand filling process and its influential factors. From experiments and comparison with conventional shooting (or blowing) process, it can be seen that this method has the advantages of better sand filling effect and less energy consumption.
