Abstract

A method of continuously forming integrally molded structures includes the steps of rotating a plurality of independently movable multisection mold assemblies (30, 31, 33) about a plurality of axes successively flowing a plurality of polymerizable mixtures over surfaces of each enclosed mold cavity while selectively heating mold sections thereof in a preselected heating profile and monitoring the flowing of each mixture, the heating of the mold sections and the formation of resins therefrom. The monitored mixture flowing, the mold section heating and the formation of each resin are coordinated with each monitored axis rotation. The molded structure is removed after it has achieved structural integrity within the mold cavity, and the steps are repeated to form a multiplicity of the integrally molded structures on a continuing basis. Also, multiaxis molding apparatus for conducting the above method.
