Abstract
A plastic table structure includes a tabletop comprising a thin polymer shell layer surrounding an expanded foam core. The multiple layers of the finished tabletop are molded concurrently in a one pass biaxial or centrifugal rotational molding process, and cured in an oven. The rotational molding process advantageously allows the shell and foam core polymer materials to be distributed into all portions of the mold. In one embodiment, a structural frame is disposed in the mold, and the foam core encases and surrounds the frame. The structural frame may be made of steel, wood, composite materials, or other materials.
