In-mold lamination of decorative products
View Patent ↗A method of manufacturing decorative plastic composites having a decorative layer, a backing layer and a clear outer layer which provides exceptional “depth of image” is disclosed. Decorative or protective appliqués' having a wide range of decorative patterns may be formed by injection molding a backing layer behind and a clear outer layer on the top surface of a thin foil, film, fabric or veneer. A method is also disclosed for coating the exposed surface of the decorative layer between injection of the backing and outer layers to impart a desired visual effect or repair the surface. Use of multiple layers of decorative film, clear plastic and colored/opaque plastic is also disclosed to provide distinguishing visual effects.
1. A method of forming an appliqué or trim product including attachment features, comprising:
providing a first decorative layer having a front side and a back side;
injection molding a first plastic layer onto said back side of said first decorative layer;
solidifying said first plastic layer;
providing a second decorative layer having a front side and a back side;
injection molding a clear plastic transparent layer onto said front side of said first decorative layer and between said first and said second decorative layers,
solidifying said second clear transparent layer;
wherein said first plastic layer includes said attachment features for said appliqué or trim panel,
wherein one of said first decorative layer and said second decorative layer includes a transparent portion, and
wherein said first and/or said second decorative layer comprises one or more of metal, wood, paper, cloth, a film, a foil, a laminate, a veneer, paint or fabric.
2. The method of claim 1 wherein said first plastic layer is colored or opaque or clear.
3. The method of claim 1 wherein said attachment features comprise one or more of hook and loop fasteners, molded bosses, molded Xmas tree projections, snap-fit surfaces, dielocks, undercuts and female features.
4. A method of forming an appliqué or trim product including attachment features, comprising:
providing a first decorative layer having a front side and a back side;
injection molding a first clear plastic transparent layer onto said front side of said first decorative layer;
solidifying said first clear transparent layer;
injection molding a second clear plastic transparent layer onto said back side of said first decorative layer, providing an exposed surface of clear plastic;
wherein said second clear plastic transparent layer includes attachment features for attaching said appliqué or trim panel;
solidifying said second clear transparent layer; and
spraying a coating of paint against said exposed surface of clear plastic,
wherein said coating of paint covers said attachment features for said appliqué or trim panel,
wherein said attachment features comprise one or more of hook and loop fasteners, molded bosses, molded Xmas tree projections, snap-fit surfaces, dielocks, undercuts and female features, and
wherein said first decorative layer includes a transparent portion.
5. The method of claim 4 wherein said coating of paint is solidified by heat from the molding of said second clear plastic layer.
6. The method of claim 4 wherein said first decorative layer comprises one or more of metal, wood, paper, cloth, a film, a foil, a laminate, a veneer, paint or fabric.
7. The method of claim 4 wherein said coating of paint is solidified by exposure to radiation.
8. The method of claim 7 wherein said radiation is ultraviolet light.
9. A method of forming an appliqué or trim product including attachment features, comprising:
providing a decorative layer having a front side and a back side;
injection molding a clear plastic transparent layer onto said back side of said first decorative layer, providing an exposed surface of clear plastic;
solidifying said clear transparent layer;
injection molding a colored or opaque plastic layer onto said exposed surface of clear plastic;
wherein said colored or opaque layer includes said attachment features for attaching said appliqué or trim panel;
wherein said attachment features comprise one or more of hook and loop fasteners, molded bosses, molded Xmas tree projections, snap-fit surfaces, dielocks, undercuts and female features, and
solidifying said colored or opaque plastic layer;
wherein said colored or opaque plastic layer covers said attachment features for said appliqué or trim panel, and
wherein said first decorative layer includes a transparent portion.
10. The method of claim 9 wherein the colored or opaque plastic layer comprises polycarbonate, acrylonitrile-butadiene-styrene or a combination thereof.
11. The method of claim 9 wherein said decorative layer comprises one or more of metal, wood, paper, cloth, a film, a foil, a laminate, a veneer, paint or fabric.
12. A method of forming an appliqué or trim product including attachment features, comprising:
injection molding a colored or opaque plastic layer in a mold;
providing a decorative layer having a front side and a back side to said mold;
injection molding a clear plastic transparent layer between said back side of said first decorative layer and in front of said colored or opaque plastic layer;
wherein said colored or opaque plastic layer includes said attachment features for attaching said appliqué or trim panel and covers said attachment features,
wherein said attachment features comprise one or more of hook and loop fasteners, molded bosses, molded Xmas tree projections, snap-fit surfaces, dielocks, undercuts and female features, and
wherein said first decorative layer includes a transparent portion, wherein said decorative layer comprises one or more of metal, wood, paper, cloth, a film, a foil, a laminate, a veneer, paint or fabric.
