PROBLEM TO BE SOLVED: To produce a precise casting of good quality that shape precision is high, internal defect is few and cast solidified structure is improved. SOLUTION: When the casting is executed by using a thin mold 1 having a prescribed shape casting space 1a in the inner part, a precasting simulation corresponding to the prescribed shape casting space 1a is executed and a failure occurring portion A caused by slow cooling in the prescribed shape casting space 1a and/or a failure occurring portion B caused by rapid cooling are beforehand detected. A mold temp. control means (cooling means 2 and/or heating means 3) for cooling the failure developing portion A caused by the slow cooling and/or for heating the failure developing portion B caused by the rapid cooling, is arranged to cool and/or heat the necessary portion in the thin mold 1 at the casting time.
