PROBLEM TO BE SOLVED: To provide a simulation apparatus for an injection molding process capable of supporting the optimum setting of the mold design, molding condition or the like of a plastic molded product. SOLUTION: The simulation apparatus for the injection molding process includes a heat transfer analyzing means for performing the heat transfer analysis of a mold and a molded product, a flow analyzing means for performing the hot fluid analysis of the filling/dwelling/cooling behavior of the molten resin in the mold and a structure analyzing means for performing the structural analysis of the molded product and the mold and estimates the shape precision of the molded product. This simulation apparatus is also equipped with a pressure/temperature calculating means for performing the heat transfer analysis of the mold and the molded product and the hot fluid analysis of the molded product individually or simultaneously to calculate the temperature of the mold, and the pressure and temperature of the molded product. The structure analyzing means sets the calculated pressure and temperature as an initial value to consider the mold and the molded product at the same time and performs structural analysis considering the mold restriction of the mold with the molded product and the viscoelastic characteristics of a resin to calculate the shape precision of the molded product deformed by thermal shrinkage.
