Abstract

La presente invención se refiere a procedimiento de fabricación de una pieza en forma de cuerpo hueco de material sintético, en especial de material sintético alveolar, procedimiento según el cual se reduce la pieza en dos partes cuyo ensamblado reconstituye la forma de la pieza a obtener, procedimiento caracterizado por el hecho de que: - se moldean piezas en bruto desmoldeables cuyo conjunto de estas formas corresponde a las partes en la que ha sido reducida la forma de la pieza a realizar, en cavidades de moldeo formadas por coquillas y machos, activando el tratamiento térmico suficientemente para estabilizar las piezas en bruto en las cavidades de moldeo sin terminar el tratamiento térmico, - después se extraen los machos dejando las piezas en bruto en las coquillas y se juntan las coquillas de tal modo que se juntan las piezas en bruto para constituir una pieza en bruto de conjunto que tenga una forma que corresponda a la de la pieza, - se termina la cocción y la estabilización térmica en el material sintético y se desmoldea la pieza terminada.
