ABSTRACT:
A panel assembly and method of manufacturing the panel assembly, especially adjusted for use in vehicle panels, include locating a preformed gasket in a support fixture in a predetermined pattern to be bonded to a sheet-like panel. The gasket is formed from a polymeric material separately from the panel. The panel is of appropriate size and geometry to fit within a desired vehicle opening. At least one panel surface to receive the gasket is prepared by being primed with a bonding reagent. The panel and primer may be preheated before receiving the gasket to drive off remaining carriers/solvents and improve the bonding process. The panel and preset gasket are pressed together such that the securing flange is in intimate contact with the panel. Locator pins may be used to properly position the panel with respect to the gasket. Once located, heat and pressure are applied, preferably substantially simultaneously, the heat being applied from a side opposite the primed surface, preferably by focused or tuned infrared irradiation.
