ABSTRACT:
An automobile interior component having sound-dampening characteristics has a contact area thereon which contacts a second interior plastic component during operation of the automobile resulting in noise. The interior plastic component has a thermoplastic elastomer self-adhered to the contact area to thereby dampen the noise created at the contact area. A method for making a sound-dampened interior plastic component includes extruding a body of thermoplastic elastomer through a die onto a contact area of an interior plastic automobile component and allowing the extruded body of thermoplastic elastomer to cool, solidify, and adhere to the interior plastic component.
