Abstract: An insert of a die for molding a speaker grille includes a forming member. The forming member defines a forming surface, from which a plurality of pins extend for forming apertures in a speaker grille. The forming surface defines a plurality of apertures disposed at spaced locations between the pins. The apertures are interconnected with a plurality vent channels communicating the apertures with the vent channels for venting air disposed in a die when melted polymer used to form the speaker grill is injected into the die. The forming member and the vent channels are formed as a monolithic construction.
