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

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.

A method of manufacturing an article having a substructure with a wall having first and second wall surfaces and a molded layer along said first wall surface, comprising the following steps: supporting said substructure in a tool having first and second die surfaces on either side of said wall, said first die surface being spaced apart from said first wall surface and said second die surface being spaced apart from said second wall surface; injecting a moldable material between said first die surface and said first wall surface under conditions causing said material to apply a varying pressure against said first wall surface between the time said moldable material is first injected to a time thereafter; and contacting said second wall surface with a fluid under sufficient pressure to create a force on said wall that offsets the pressure exerted by said material and changing the pressure of said fluid in accordance with a predetermined time/pressure relationship, whereby said wall is supported against deformation.
