Plastic panels which are useful as automotive interior trim panels, interior door panels and the like decorative and structural panels, are made by a method which integrates insert sections in the surfaces of the panels and eliminates insert edge trim molding strips. The method includes bonding at least the edge portions of the inserts upon a thin plastic sheet, pre-sized blank, then removing the plastic sheet portions that overlap the insert within the bonded portions; next, positioning the blank in a mold against a mold face and molding in situ and simultaneously bonding a plastic substrate against the blank and the exposed surface of the insert. A substantially continuous, channel forming means, such as a narrow rib or a groove, on the mold face, is overlapped by the bonded insert edge portions and sheet portion, which are folded by said means to form a narrow, relatively deep channel. The insert edges are part of and, consequently, are concealed within the channel. The channel forms an edging around the insert in the completed panel surface. Thus, the composite sheet and insert forms an exposed, decorative surface on the molded plastic panel. |

DETAILED DESCRIPTION FIG.
1 schematically illustrates an example of an interior door panel 10 for an automobile.
The panel 10 is illustrated as being formed with curved opposite ends.
It is sized and shaped to fit within a sheet metal door for trimming the interior of the door within the passenger compartment of a vehicle.
The panel includes, for illustration purposes, an upper panel insert 11 which may have an interior face formed so as to simulate a wood grain appearance.
Similarly, a lower insert 12 is positioned in the panel and may be formed of a pile, carpet-like material, to simulate a carpeted section of the panel.
The panel may be provided with various openings or receptacle areas, after the molding is completed, to receive some of the hardware which is typically mounted within a vehicle door.
These openings or areas may be cut or punched in the panel.
For example, the panel may have a square or oblong opening 13 to receive a block of switches which operate the window actuating motors, and a round opening 14 which may receive a switch for actuating the exterior side view mirrors.
Different size and shape openings and receptacle areas may be molded in the panel as required.
The interior surface 15 of the panel may be formed with embossments or may be textured.
These decorative surface configurations may be formed during the molding of the panel door or may be preformed in the sheet or blank utilized in the molding.
The molding process involves starting with a sheet 18 which is cut or formed into a desired size to provide a blank for molding purposes.
Preferably, the sheet is selected from a thin, plastic film, such as a 20 mil thickness vinyl plastic material.
Other suitable plastic sheet materials, of appropriate thicknesses, may be selected for this purpose.
The sheet may have a face which is pre-embossed or pretextured.
Alternatively, it may be textured or embossed during the molding process in the mold.
The next step in the process involves positioning the inserts, as for example, the upper insert 11 and the lower insert 12, upon one face of the blank, as illustrated in FIG
