Abstract: PROBLEM TO BE SOLVED: To provide a method for evaporative pattern casting, capable of easily determining a condition where a casting having no residual defect and excellent qualities is produced. SOLUTION: The casting is produced by pouring molten metal into a mold where a pattern made of a synthetic resin foam is laid in foundry sand, while evaporating the pattern by molten metal. The pouring time t (S) of molten metal is determined based on the pouring time t ∞ (S) of the molten metal in a void casting where an internal pressure is not applied. COPYRIGHT: (C)2004,JPO
