Abstract

A method of manufacturing an injection molded object having an outer shell with a front face and a light transmitting assembly molded into the outer shell which assembly is visible from the front face. The method includes the following steps. Supporting a light transmitting assembly on a mold projecting tool which is closable with a mold cavity tool having an interior wall which defines the front wall of the outer shell. Forming narrow passages through the light transmitting assembly to connect its front and rear faces. Closing the mold to position the front face of the light transmitting assembly adjacent the interior wall of the mold cavity tool while leaving a narrow peripheral recess therearound in communication with the narrow passages. Injecting a molten plastic into the closed mold to form the outer shell of the object while also flowing the molten plastic through the narrow passages in the light transmitting assembly and the narrow peripheral recess between the front face of the light transmitting assembly and the interior wall of the mold projecting tool. Separating the injected plastic filling the narrow passages of the light transmitting assembly from the injected plastic filling the narrow recess upon separation of the mold projecting tool and the mold cavity tool.
