A method of making an electrically conductive and weatherproof enclosure includes mixing and melting an electrically conductive material, a latex rubber material, and a polycarbonate material to produce a weatherproof material mixture, blending carbon black with polyethylene to produce an electrically conductive additive, positioning an injection mold of the enclosure in fluid communication with an exit end of a heating barrel, injecting the weatherproof material mixture into an entry end of the heating barrel, introducing the electrically conductive additive through a lateral port of the heating barrel proximate to the exit end to partially mix with the weatherproof material mixture to produce an injection mixture, and injecting the injection mixture into the injection mold to produce the electrically conductive and weatherproof enclosure.
