ABSTRACT:
A method of manufacturing an article having a substructure with a wall having first and second wall surfaces and a molded layer along the first wall surface. The substructure is supported in a tool having first and second die surfaces on either side of the wall. The first die surface is spaced apart from the first wall surface and the second die surface is spaced apart from the second wall surface. A moldable material is injected between the first die surface and the first wall surface under conditions causing said material to exert a force on the wall. The second wall surface is contacted with a fluid under sufficient pressure to create a force on the wall that offsets the force exerted by the material whereby the wall is supported against deformation.
