A method of manufacturing a plastic window for an automotive vehicle in which a hollow frame portion is separately molded from a main optical panel the frame portion bonded to the perimeter of the main panel as by melt bonding.

Process for manufacturing a molding plastic window for an automotive vehicle and window produced thereby

A window panel for use in automotive glazing applications is described, in which inner planer piece transparent plastic is bonded to an outer piece molded from an opaque plastic creating a masking border. The two pieces have overlapping portions, and may be of reduced or tapering thickness to create a transition masking zone of reduced or varying opacity. The inner piece may be designed to separate from the outer piece at a lower impact force than that required to fracture the pieces to establish a prescribed failure mode. The window panel may be formed by a two shot molding process in which the inner and outer pieces are molded respectively to increase the overall window panel size beyond that able to be molded by a one shot process.
