Methods and materials for conduit apparatus and electrical enclosures

Abstract

An enclosure and a method of making the enclosure is provided that includes mixing stainless steel, rubber, and polycarbonate to produce a material mixture that is electrically conductive. Carbon black powder and polyethylene are blended to produce an electrically resistive additive for dissipating static electricity. At least one injection mold for the enclosure is positioned in fluid communication with an exit end of a heating barrel. The weatherproof material mixture is injected into an entry end of the heating barrel to produce a melted weatherproof material mixture. The electrically resistive additive is introduced through a lateral port of the heating barrel proximate to the exit end to partially mix with the melted weatherproof material mixture to produce an injection mixture. The injection mixture into the at least one injection mold to produce the enclosure that is weatherproof, electrically conductive, and electrically resistive.
