## Abstract

A decorative molded part with a decorative sheet provided on the visible side and is connected to a substrate, and to a method of manufacturing the same. In the method, a plastic layer is arranged between the substrate and the decorative sheet. Edge sections of the decorative sheet projecting beyond the substrate on both sides are bent around the substrate together with the plastic layer for positive enclosure of the substrate within the decorative sheet.

## Claims

### Claim 1

A method of manufacturing a decorative molded part with a decorative sheet on a visible side of the decorative molded part and connected to a substrate, comprising the steps of:
arranging a plastic layer between the substrate and the decorative sheet, wherein edge sections of the decorative sheet project beyond the substrate on both sides thereof; and
bending the edge sections around the both sides of the substrate enclosing the plastic layer to form a positive enclosure of the substrate within the decorative sheet,
wherein the substrate and the plastic layer are connected to each other exclusively by the positive enclosure, the substrate is injection molded as a molded part, and the substrate is formed from a foamed plastic.

### Claim 2 (depends on 1)

The method according to claim 1, wherein surface sections of the decorative sheet are covered with the plastic layer before said step of bending the edge sections.

### Claim 3 (depends on 2)

The method according to claim 2, wherein the decorative sheet and the plastic layer are placed one on top of the other as flat semi-finished products and cut to contour before said step of bending the edge sections.

### Claim 4 (depends on 3)

The method according to claim 3, wherein the plastic layer and the decorative sheet are cut to the same contour.

### Claim 5 (depends on 1)

The method according to claim 1, wherein at least one rear side surface section of the substrate is omitted from said step of bending the edge sections.

### Claim 6 (depends on 1)

The method according to claim 1, wherein the substrate is at least partially surrounded by the decorative sheet by said step of bending the edge sections.

### Claim 7 (depends on 1)

The method according to claim 1, wherein the substrate is at least partially surrounded by the decorative sheet and the plastic layer by said step of bending the edge sections.

### Claim 8 (depends on 1)

The method according to claim 1, wherein the substrate is at least partially surrounded by the plastic layer by said step of bending the edge sections.

### Claim 9 (depends on 1)

The method according to claim 1, wherein the plastic layer is formed from a foamed plastic.

### Claim 10 (depends on 1)

The method according to claim 1, wherein the substrate and the plastic layer are connected to each other and to the decorative sheet exclusively by the positive enclosure.

### Claim 11

A method of manufacturing a decorative molded part comprising the steps of:
forming a foamed plastic substrate having a periphery and a front side and a rear side by injection molding, the rear side having attachment pins;
placing a decorative sheet on a plastic layer;
punching the decorative sheet and the plastic layer forming a contour having edge sections;
applying the decorative sheet and the plastic layer of the contour to the substrate with the plastic layer between the decorative sheet and the substrate and the edge sections of the contour extending beyond at least opposing ends of the periphery of the substrate; and
bending the edge sections of the decorative sheet and the plastic layer of the contour over the periphery of the substrate from the front side to the rear side forming a positive enclosure of the substrate with the decorative sheet and the plastic layer of the contour wherein the decorative sheet is fixed to the substrate by the edge sections of the contour, wherein the substrate and the plastic layer are connected to each other exclusively by the positive enclosure,
whereby the substrate, decorative sheet, and the plastic layer a capable of being easily separated for cost-effective recycling.

### Claim 12 (depends on 11)

The method of manufacturing a decorative molded part according to claim 11 wherein:
the plastic layer comprises foam.

### Claim 13 (depends on 11)

The method of manufacturing a decorative molded part according to claim 11 wherein:
the decorative sheet comprises aluminum.
