  • Process for manufacturing foam-filled extruded products
    Patent number: 5728330
    Abstract: A process for fabricating an article having a rigid foam core and a resilient outer plastic shell by extruding a heated thermoplastic material to form the shell, partially hardening the extruded plastic shell, injecting a liquid foam material into the interior of the partially hardened plastic shell, and cooling the shell and the liquid foam material to fully harden the plastic shell and the foam under conditions which cause the article to have a predetermined shape and size.

  • Foam-filled extruded decking plank and decking attachment system
    Patent number: 5660016
    Abstract: An extruded plastic decking plank for mounting to an underlying support structure, the plank having a rigid foam core, a resilient outer plastic shell, and a clamping portion for securing the plank to the support structure. The top surface of the plank can be provided with a non-slip surface. The invention also includes an attachment system for securing such decking planks to a support structure by engaging the clamping portions of the decking planks onto clamps or hold down blocks which are secured onto the support structure, and which permit relative motion between the planks and the structure in the planks' lengthwise direction to prevent stress and buckling caused by uneven expansion.
