Abstract
A process for forming a product having multiple and well defined color patterns. In a first embodiment, the rotomolding process comprises a first step of using a first powder having a first color and a second powder having a second color which is different than the color of the first powder. The rotomolding process comprises a second step of placing the first and second color powders into a pre-determined pattern within a hollow cavity mold. The rotomolding process comprises a third step of placing the closed hollow cavity mold into the oven. The rotomolding process comprises a fourth step of heating the hollow cavity mold with no rotation for a first period defined by the heating time necessary for a layer of individual colors to melt in the desired pattern upon the inside surface of the hollow cavity mold. The rotomolding process comprises a fifth step of rotating the hollow cavity mold in a bi-axis manner while heating the hollow cavity mold for a second period of time defined by the heating time necessary to completely melt the remaining material in the hollow cavity mold. The rotomolding process comprises a sixth step of cooling the hollow cavity mold to solidify the product. The rotomolding processes comprises a seventh step of removing the product from the hollow cavity mold. The resulting product comprises a first color pattern having the color of the first color powder and a second color pattern having the color of the second color powder.
