Rotomolding (or spincasting) is a very effective and simple way to achieve hollow forms in casting, which would not be otherwise possible. The basic machine essentially spins on two perpendicular axes, containing a mold filled with concrete, or some other type of casting material, forcing it to the exterior of the mold shell. As the material solidifies, a hollow form is left in the center, and a layer of hardened material on the exterior. Our engineered rotomolding machine is meant to do just that, and through various trials using a wood prototype, a final aluminum version was made possible.
