  • Publication number: 20070122591
    Abstract: Thermoforming of plastic sheets over a model includes varying the thickness in the area that is stretched over the model so that when it thins it becomes more uniform in thickness. The plastic sheet is fabricated in a substantially uniform thickness but with a preformed a complex profile or 3D area that partially builds in part of the area that would be stretched so that it thins much less than a flat sheet. Combinations of these elements may also be made.

  • Publication number: 20070122592
    Abstract: A sheet (10, 20) for use in a model vacuum thermoforming process, wherein the sheet (10, 20) has a thickened area (11) that may be in a preselected three-dimensional form such as arch-shape (12). The thickened area (11) or three-dimensional area (12) is placed over an area of the model (21) where the plastic sheet is to be stretched during the thermoforming process. This ensures a uniform or a preselected thickness in the stretched areas than would otherwise occur.
