PROBLEM TO BE SOLVED: To provide a method for setting injection molding conditions for manufacturing a molding with the generation of a secondary weld suppressed easily at low cost and an injection molding method. SOLUTION: In the injection molding method for forming the molding by using a mold having at least two gates and injecting a molding material into each gate, at positions to be symmetric in relation to a confluence surface where flows of the molding materials injected from different gates into the mold join together, internal pressures of the flows are made approximately equal while the molding material is packed in the mold after the flows are joined together. The molding conditions are set so that the internal pressures are anticipated by a processing means and determined to be approximately equal. COPYRIGHT: (C)2005,JPO&NCIPI
