Title: Method of forming a windowed unitary panel
Inventor: GRAWEY CHARLES E
IPC: E06B3/20
Filed: 1984-08-24
Abstract: A method of forming a windowed unitary panel (10) having a peripheral edge portion (14) of a windowpane of glazing (12, 13) integrally embedded within a frame (11) 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.
