Extruded automotive trim and method of making same
View Patent ↗An automotive trim product is made as follows. A single or multiple layer sheet is extruded so as to include at least one color pigmented and/or metallized layer therein. Optionally, a clear coat may be laminated to the sheet, or may even be coextruded therewith. In certain embodiments, a roughened surface texture may be embossed into a major surface(s) of the sheet prior to lamination. In other embodiments, a design (e.g., logo) may be silk-screened onto the clear coat layer prior to lamination. The sheet, after optional lamination, is then thermoformed into a three-dimensionally shaped preform or article via vacuum forming or the like.
1. A method of making a colored automotive trim product, the method comprising:
extruding an approximately planar sheet including at least a colored layer, the colored layer including color pigment material and metallizing material;
causing the approximately planar sheet, having first and second major surfaces, to pass by at least one embossing roller which embosses a roughened surface texture into or onto the first major surface of the approximately planar sheet, wherein the roughened surface texture comprises an orange peel roughened surface texture;
laminating the approximately planar sheet to at least a clear coat layer so that after laminating the first major surface of the approximately planar sheet having the roughened surface texture is closer to the clear coat layer than is the second major surface of the approximately planar sheet in a resulting laminate; and
after laminating, positioning the laminate in a vacuum-forming apparatus and vacuum-forming the laminate into a three-dimensionally shaped article.
2. The method of claim 1 , wherein the orange peel roughened surface texture includes a plurality of bumps having an average wavelength of from 0.5 to 10 mm.
3. The method of claim 1 , wherein said laminating comprises laminating the clear coat layer directly to the first major surface of the sheet having the roughened surface texture so as to be in direct contact therewith.
4. The method of claim 1 , wherein said laminating comprises laminating the clear coat layer to the first major surface of the sheet having the roughened surface texture with at least one tie layer therebetween.
5. The method of claim 1 , further comprising:
providing the three dimensionally shaped article in a cavity of an injection molding apparatus;
injecting heated semi-molten or flowable material into the cavity of the injection molding apparatus so that the semi-molten material bonds to the three-dimensionally shaped article to form a shaped article;
removing the shaped article from the injection molding apparatus; and
using the shaped article as at least part of an exterior trim product for a vehicle.
