<p>In the injection molding apparatus (30), a first heater (44) and a second heater (46) are embedded in the concave die (32) for molding the design surface (24) of the resin molding (10). The surface layer of a molten resin (14, 16), to which aluminum flakes (12) have been added, that will become the design surface (24) is heated by the first heater (44) and the second heater (46) and maintained in a flowable state. Pressure is applied on the molten resin (14, 16) supplied from each of multiple gates including gates (56a, 56b) after the molten resin meets inside the cavity (52). As a result, reorientation of the aluminum flakes (12) occurs on the uncured design surface (24) and internally.</p> |
