Abstract

A method for forming and selectively decorating a molded resin panel 10 begins with vacuum forming an applique 15 of decorative resin material and fitting applique 15 in an injection molding cavity. Base 11 is then injection molded to applique 15, and a mask 20 is formed to fit over applique 15. A decorative coating 18 is applied over the panel regions not covered by the mask. A resin undercoating 17 is applied under decorative coating 18 which is covered with a top coating 19 of clear resin material.

Claims

1. A method of forming and selectively decorating a molded resin panel, said method comprising:

a. vacuum forming an applique of decorative resin material;

b. die cutting said applique to form a predetermined peripheral edge;

c. fitting said applique in an injection molding cavity;

d. injection molding said panel to said applique so said panel extends beyond said applique and has a recess in the region of said edge of said applique;

e. forming a mask to fit over said applique;

f. fitting said mask over said applique so a periphery of said mask is disposed in said recess;

g. applying a decorative coating over regions of said panel not covered by said mask; and

h. preceding said decorative coating with an undercoating of resin material under said decorative coating and following said decorative coating with a top coating of clear resin material over said decorative coating.

2. The method of claim 1 including removing said mask and applying said top coating to extend over said applique.

3. The method of claim 1 including applying said undercoating of clear resin material before fitting said mask so said undercoating extends over said applique.

4. The method of claim 3 including removing said mask and applying said top coating to extend over said applique.

5. The method of claim 1 including forming said decorative coating as a metallized layer.
