<p>PROBLEM TO BE SOLVED: To provide an injection molded article that is closer to the design value thereof.SOLUTION: The injection molded article is obtained via: a resin injection step in which thermoplastic resin in molten state is injected into a cavity CT provided with a plurality of gates GT1 and GT2; and a resin cooling step in which the molted state thermoplastic resin injected into the cavity CT is solidified. In the resin injection step, thermoplastic resin in molten state is injected into the cavity CT from one or more than two gate GT1 while the temperature difference between the molten state thermoplastic resin and the metal mold constituting the cavity CT is 50°C or less, after that, thermoplastic resin in molten state is injected into the cavity CT from other one or more than two gate GT2 different from gate GT1 into which the molten state thermoplastic resin is injected previously. The thermoplastic resin is a designated resin and contains one or both of bright pigment and black pigment.</p> |
