Method of making a fabric-less part
View Patent ↗A fabric-less part and a method of making same are disclosed. The fabric-less part may include a flexible polyurethane foam body, a high-density polyurethane foam backing layer bonded to the foam body, and a polyurethane elastomer skin bonded to the backing layer. Alternatively, the backing layer may be eliminated and the polyurethane elastomer skin is directly bonded to the flexible polyurethane foam body. The fabric-less part may be an automotive interior part such as a pillar trim, headrest, trim panel, instrument panel, door panel, armrest, or part of an automotive seat such as a seat cushion.
1. A method of making a fabric-less part, the method comprising:
spraying a polyurethane elastomer on an article-defining surface of a mold to form a polyurethane elastomer skin;
dispensing a high-density polyurethane foam on the polyurethane elastomer skin to form a backing layer bonded to the skin;
pouring a flexible polyurethane foam on the backing layer to form a foam body bonded to the backing layer; and
dispensing high-density polyurethane foam on the foam body to form a second backing layer bonded to the foam body.
2. The method as claimed in claim 1 further comprising spraying a coat on the article-defining surface before spraying the polyurethane elastomer.
3. The method as claimed in claim 1 further comprising spraying a polyurethane paint on the polyurethane elastomer skin to form a top coat on the part.
