Un poste hueco moldeado por centrifugación que comprende: Un miembro de poste hueco alargado, que tiene dimensiones externas cónicas, que está formado mediante moldeado centrífugo caracterizado porque el poste tiene un espesor de pared sustancialmente uniforme a través del eje longitudinal de dicho miembro de poste, y porque la superficie exterior de dicho miembro de poste está texturizada con una pluralidad de granos u ondulaciones.
Herein disclosed is a centrifugally cast pole having a substantially uniform wall thickness along the long axis of the pole. During centrifugal casting, molten metal is poured inside a rotating, tapered mold. As chilled liquid is poured over the outside of the rotating mold, the metal forms, or paints, to the contour of the mold interior creating a metal pole. By precisely controlling casting gyrations such as the spin, travel, pitch, and yaw of the rotating mold and the calibration and physical mechanisms of the casting machine, hollow, tapered, tubular metal poles are produced with previously unknown uniformity of wall thickness. The controlling principles, designs, and mechanisms of this centrifugal casting method enable wall uniformity to extremely high tolerances. By extension, the ability to precisely control the metal volume painted inside the mold allows, as a design choice, wall thickness variation in any embodiment if so desired.
