A polymeric composite structure having a polymeric shell layer with a finish-side and a non-finish side and a cross-linked thermosetting polymeric backing layer and method of manufacturing thereof is provided. The cross-linked thermosetting polymeric backing layer is simultaneously molded to conform to the shape of and bonded directly to essentially the entire non-finish side of the polymeric shell layer. The method includes forming the polymeric shell having a finish-side and non-finish side into a suitable shape, placing the shell into a mold, and introducing an uncured blended mixture of unsaturated thermosetting polymeric backing material and cross-linking promoter into the mold to force the backing material to directly coat the non-finish side of the shell. Curing the molded thermosetting polymeric backing material at a suitable temperature and sufficient time allows hardening and cross-linking of the thermosetting polymeric material and bonding directly to the non-finish side of the polymeric shell to permit demolding of the composite structure without damage.

Polyester backed acrylic composite molded structure and method of

A molded article and the mold for making molded articles are disclosed. The molded article is a sanitary fixture, such as a whirlpool bathtub. The molded article comprises a rigid shell having a finish side and a non-finish side. A rigid material is coated on the rigid shell and integrally forms a leveling base on the bottom side of the rigid shell. Mounting pockets for attaching an apron and mounting areas for attaching a whirlpool motor may also be integrally formed in the rigid material coated on the rigid shell. The mold for manufacturing includes a plurality of cavities for forming leveling runners on the bottom side of the molded article. Additional cavities may be included in the mold for forming mounting areas and mounting pockets on the molded article.
