Method of forming a windowed unitary panel

摘要

A method of forming a windowed unitary panel having a peripheral edge portion of a windowpane of glazing integrally embedded within a frame of high modulus plastic material includes heating the pane to a preselected temperature prior to its being positioned within a mold. The peripheral edge portion of the windowpane protrudes into the mold cavity so that the high modulus plastic material forming the frame encapsulates the peripheral edge portion. This prevents buckling of the windowpane since the preheated windowpane contracts simultaneously with the contraction of the rigid frame as it cools from the molding temperature to ambient.
