<p>The method involves performing multilayer injection with successive injections of inner layer (3), intermediate layer (6) drowned in a thickness of a final part and outer layer (7), where each plastic material layer corresponds to a fraction of the thickness of the final part and the layers are made of same or different materials. A rotating part of mold possessing indexed angular positions is utilized at each corresponding injection position of the one of the layers.</p> |
