Abstract

Un método para la producción de un artículo hueco, tal como una pelota inflable para deportes, que comprende una capa externa de material, y una capa interna de material donde dicho método comprende las fases de cargar un molde de fundición giratorio con el material de la capa externa; calentar y hacer girar el molde para distribuir la carga sobre la superficie del mismo y fundir parcialmente la carga; abrir el molde y romper la carga parcialmente fundida, cargar el molde con una segunda carga, cerrar nuevamente el molde y continuar la rotación y el calentamiento para formar la capa interna y completar la fusión de la capa externa, caracterizado dicho método porque la segunda carga comprende una primera resina termoplástica y una segunda resina termoplástica una de las cuales posee una resistencia a la tracción superior que el material de la capa externa y porque las dos resinas de la capa interna forman estructuras de retículo entrelazadas mecánicamente rellenando el material de una estructura de retículo los intersticios de la otra estructura de retículo y viceversa.
