Abstract:
A method of continuously forming an integrally molded structure in a multiaxis rotational molding operation including the steps of rotating a multisection mold assembly about at least three axes, flowing a first freshly formed polymerizable mixture over surfaces of an enclosed mold cavity within said multisection mold assembly, monitoring said flowing of said first mixture over said mold cavity surfaces and formation of a first resin therefrom, flowing a freshly formed rapidly gelling second polymerizable mixture into said mold cavity, depositing a preselected quantity of said second mixture into contact with a first preselected area of said first resin, drawing a portion of said deposited second mixture as it is gelling toward a second preselected area remote from said first preselected area at a rate to form therefrom a continuous support member with structural integrity extending between said preselected areas of said first resin, continuing said rotation of said multisection mold assembly throughout said steps of said continuous molding operation while monitoring individually each axis rotation of said multisection mold assembly, and coordinating said monitored flowing of each mixture and said monitored formation of each resin with each monitored axis rotation in a preselected profile to form said integrally molded structure of said first and second resins, separating said mold sections of said multisection mold assembly, removing said integrally molded structure from said separated mold sections and repeating said steps to form a multiplicity of said integrally molded structures of said first and second resins on a continuing basis.
