A method and apparatus for forming an interior component part having a relatively rigid substrate portion and a padded portion. The molding tool used to form the substrate portion includes a first mold part and a second mold part that form a substrate molding cavity into which a thermoplastic olefin is injected. The padded portion is formed by the first mold part and a third mold part that define a pad forming cavity. A mixture of a thermoplastic elastomer and a blowing agent is injected into the pad forming cavity. The expanded blown elastomer is enveloped within a skin formed when the blown elastomer contacts a cooled mold surface.
