ABSTRACT:
A method of manufacturing an article having a substructure with a wall having a wall surface and a foam layer along the wall surface, including the steps of: placing the substructure in a tool having a die surface being spaced apart from the wall surface; injecting a foamable material between the die surface and the wall; applying a clamp load between the die surface and the foamable material; allowing the foamable material to expand and exert a force on the wall; and reducing the clamp load on the foamable material to reduce the force exerted on the wall by the expanding material whereby the force exerted on the wall does not deform the article.
