Abstract

Una maquina calibradora cilindrica, que reduce el diametro exterior de la pared interior a una longitud deseada a medida que pasa desde el punto de entrada de la pared interior semisolida hasta el punto final; un pasaje de flujo de refrigerante, para suministrar refrigerante, se forma dentro de la matriz de pared interior y de la maquina calibradora de la pared interior; se instala una barra de soporte de guia, desde la matriz de pared interior hasta el interior de la maquina calibradora de la pared exterior; una guia de pared interior soportada por la barra de soporte de guia instalada en la maquina calibradora de la pared exterior en la posicion en la que se produce la conformacion; y la pared interior semisolida pasa entre la guia de la pared interior y la pared exterior esta conformada para una estrecha integracion con la pared exterior por medio de presurizacion.
