Continuous molding apparatus includes a raw material supplying portion, a molding portion, a supporting portion, a mixing portion and a control portion. Each reservoir of the raw material supplying portion is connected independently with the mixing portion. The molding portion includes a plurality of spaced mold assemblies each with at least two separable mold sections. The supporting portion includes a plurality of the spaced mold assemblies each supported for independent rotation about more than one axis. The mixing portion includes an elongated mixing chamber disposed adjacent each mold assembly each with a plurality of deflector sections. A continuous method of molding a foamed product includes providing a plurality of raw material reservoirs and continuously moving raw material from each reservoir independently to a plurality of spaced mixing chambers each of which is located adjacent to an individual mall assembly including separable mold sections. The raw materials are introduced into the mixing chambers and pass a freshly formed mixture flowing therefrom directly into a cavity of the adjacent mold assembly. Each mold assembly is rotated about more than one axis to flow the mixture over all surfaces of the mold cavity. The rotational movement of the mold assembly is continued while the mixture forms a foam. The delivery of raw materials to each mixing chamber and the mixture flowing therefrom and the multiple axis rotation of each mold assembly is monitored. Also, the molded product produced by the method and apparatus.
