ABSTRACT:
A molding station for molding a colored product of a synthetic resin mixed with a colorant and a coating station for applying a colored clear coat to the surface of the molded colored product are disposed adjacent to each other for highly efficient production of colored clear coated, molded colored products. The molded colored product is charged directly from the molding station into the coating station. The hue of the molded colored product and the hue of the colored clear coat are seen as mixed to the eye. A plurality of hues may be available for each of the colorant and the colored clear coat, so that a variety of hues can be achieved on colored products by a combination of hues of the colorant and the colored clear coat without maintaining a large stock or inventory of different colorants or colored clear coats. The facility required to color the above products is relatively small in size, and the coloring processes are composed of a relatively small number of steps in comparison to conventional apparatus and methods.
