Abstract

UN OBJETO 18 SE COMPONE DE POLVO COMPACTADO Y TIENE UN DISCO 19 Y UNA PROYECCION COLUMNAR CORTA 20 QUE SE EXTIENDE DESDE EL DISCO 19. LA PROYECCION COLUMNAR CORTA 20 TIENE UNA PARTE AHUSADA 24 EN FORMA DE CONO TRUNCADO Y UNA PARTE VERTICAL 25 EN FORMA DE CILINDRO. A FIN DE FORMAR LA PROYECCION COLUMNAR CORTA 20 ORIENTADA HACIA ARRIBA, SE INTRODUCE EL POLVO P Y SE COMPACTA EL POLVO ACCIONANDO LOS PUNZONES SUPERIOR E INFERIOR. DURANTE LA COMPACTACION, SE FORMA PRIMERO EL DISCO 19. DESPUES SE FUERZA EL FLUJO DEL POLVO P DESDE UNA REGION DE FORMACION DE DISCO A HASTA UNA REGION DE FORMACION DE PARTE VERTICAL B A TRAVES DE UNA REGION DE FORMACION DE PARTE AHUSADA C, FORMANDO ASI LA PROYECCION COLUMNAR CORTA 20. EL OBJETO 18 CON LA PROYECCION COLUMNAR CORTA (20) ORIENTADA HACIA ARRIBA SALE SIN CAMBIAR SU ORIENTACION. POR CONSIGUIENTE, EL OBJETO 18 SE COMPONE DE POLVO COMPACTADO Y TIENE UNA PROYECCION COLUMNAR CORTA CON UNA DENSIDAD REQUERIDA SIN DIFICULTAD ALGUNA.
