The invention discloses an EMI shielding enclosure having one or more EMI shielding vents as its integral part thereof. The enclosure as well as the vent is molded from a thermoplastic material filled with a conductive filler. Metal fibers, particles, flakes or metal-coated fibers are used as a filler to provide conductivity to otherwise dielectric thermoplastic matrix. Molding is done using available techniques such as injection molding and extrusion. In one particular configuration, the EMI vent is molded as a separate entity. Features such as bosses and grooves are provided on the vent to enable easy attachment with the shielding enclosure
