Abstract: A method of molding an article between a pair of spaced molded walls comprises the steps of releasably attaching a first member to one mold wall, releasably attaching a second member to the other mold wall in alignment with but spaced from the first member, connecting the two spaced members together by a yielding connection, and introducing heated molding material between the two mold walls, whereby when the molded article cools, the yielding connection yields to accommodate shrinkage deformation of the article. Also described is apparatus for use in performing the above method.
