ABSTRACT:
A method of manufacturing a panel unit constituted of a panel and a frame provided on the periphery of the panel. The method comprises the steps of providing a first die having a molding groove and a panel receiving space formed therein, and a second die engageable with the first die and having a molding groove formed therein, mounting the first die on the periphery of the panel, engaging the second die with the first die to form on the periphery of the panel a molding space of which the cross-sectional configuration corresponds to that of the frame, extruding molding material into the molding space, and applying relative motion between the second die and the first die to move the second die along the first die, thereby integrally forming the frame on the periphery of the panel.
