    摘要： A method of continuously forming an integrally molded structure in a multiaxis rotational molding operation includes the steps of rotating a multisection mold assembly about at least three axes. A first freshly formed polymerizable mixture is flowed over surfaces of an enclosed mold cavity within the multisection mold assembly. The flowing of the first mixture over the mold cavity surfaces and formation of a first resin therefrom is monitored. A second freshly formed polymerizable mixture is flowed under pressure through an orifice into the mold cavity. A liquid stream of the second mixture is formed. The liquid stream is gelled as it advances through the mold cavity to form a continuous filament with structural integrity. The filament is contacted with the first resin formed within the mold cavity. The filament is distributed over the first resin in a preselected pattern. A third freshly formed polymerizable mixture is flowed over the filament pattern formed within the mold cavity with the second mixture. The flowing of the third mixture and formation of a third resin therefrom is monitored. The rotation of the multisection mold assembly is continued throughout the steps of the continuous molding operation while monitoring individually each axis rotation of the multisection mold assembly. The monitored flowing of each mixture and the monitored formation of each resin with each monitored axis rotation is coordinated in a preselected profile to form the integrally molded structure of the first, second and third resins. Also, apparatus forming the structure.

    摘要： The physical properties of reaction injection molded (RIM) polymeric articles are substantially improved by internally reinforcing them with flake glass filler particles. The flake glass is incorporated in the liquid chemical polymer precursors, and is co-injected with them into the mold. The flow of the liquids in the mold orients the glass flake to provide maximum improvement in physical properties in the hardened polymerized article. Molding with glass flake filler also substantially alleviates problems of surface waviness in RIM panels.
