Method of manufacturing an interlocked, “flush-to-front,” injection molded border and glass sheet

Abstract

The method of the present invention is performed by providing a glass sheet having first and second opposite surfaces merging with each other along a peripheral ground angled surface setting-off with the glass sheet first surface an included angle substantially greater than normal. The glass sheet is placed in a mold having opposing cavity portions which collectively define a cavity including a peripheral edge cavity portion defined in part by a cavity defining surface which lies in the plane of the glass sheet first surface when the mold is closed. The mold is then closed such that the cavity defining surface and the glass sheet round angled surface set-off and angled complementary to the included angle and with the glass sheet per surface abutting the cavity defining surface inboard of the glass sheet -ground angled surface. Polymeric/copolymeric synthetic plastic material is injected into the peripheral cavity portion to completely encapsulate the glass sheet periphery with a border, frame or encapsulation having a first exterior surface coplanar with the glass sheet first surface whereby the latter two surfaces are “flush-to-front” and the glass sheet periphery is in undercut interlocked relationship with the injection molded border.
