Abstract
An elongated structural article, having a continuous profile extrusion with spaced apart layers defining a portion of a cavity filed filled with thermoplastic pre-expanded beads expanded with steam in-situ causing the beads to securely bond together and to the profile extrusion. The article is cut to a length forming ends having an exposed foam core. A system for manufacturing the article is also disclosed having a profile extrusion die for forming an axially profile defining a wall surrounding a cavity, a tubular shaping mold located axially downstream of the extrusion die sized to support a length of the profile as it passes there through. A bead dispenser is oriented to introducing pre-expanded beads into the profile cavity while within the shaping fixture and a steam tube is oriented downstream of the introduction of pre-expanded beads. Control valves regulate the flow of pre-expanded beads and steam into the profile cavity.
