| Abstract: | Stability conditions of the moulding sand at the mould top in EPC process are investigated theoretically. The necessary mechanical conditions are presented respectively for the moulding sand at the mould top to be without the defect of collapse and rise at the end of mould filling, and the influence of relevant processing factor on above-mentioned defects is also discussed according to those conditions presented. |

| Keywords: | EPC process moulding sand stability collapse defect rise defect mechanical conditions |
