Abstract
A process and apparatus is provided for molding flowable materials. The mold may be provided with deformable or collapsible mold surfaces and a forming member which is positioned in the mold when producing a shell molded article is also deformable or collapsible. After the molded article is formed the forming member and/or the mold surfaces are deformed or collapsed to facilitate removal of the article from the mold and to avoid 'backlocking' of the article in the mold.
