Abstract: A guard rail post is molded from a plastic recycled material which is reinforced with a vertical and a horizontal reinforcing member embedded within an L-shaped plastic body.

Abstract: Apparatus for molding an elongated cylindrical object includes an elongated cylindrical mold. First and second closure plates are positioned within the mold and an elongated tube is suspended between the closure plates within the mold. A sliding piston is mounted over the elongated tube. Molten plastic is introduced into the mold between the piston and one of the closure plates so as to cause the piston to slide along the tube within the mold toward the opposite closure plate. When the mold is filled, the piston engages the opposite closure plate, and further introduction of molten plastic is stopped. This process produces an elongated plastic body having the tube embedded therein.
