Abstract

PROCEDIMIENTO DE FABRICACION DE PIEZAS INTERMEDIAS PARA EL MOLDEO POR SOPLADO DE ENVASES. CARACTERIZADO PORQUE EL MATERIAL, ORIGINALMENTE EN FORMA DE TUBO, QUEDA DOTADO DE UN ESPESOR SUSTANCIALMENTE REDUCIDO EN LA ZONA CENTRAL. EN UNA PRIMERA FASE SE REALIZA EL ESTIRADO DEL TUBO EN DIRECCION AXIAL POR CALAENTAMIENTO EN LAS ZONAS ORIENTADAS A UNA TEMPERATURA POR ENCIMA DE LA TEMPERATURA DE TRANSICION A ESTADO VITREO. EN UNA SEGUNDA FASE SE LLEVA A CABO LA EXPANSION EN DIRECCION RADIAL DEL TUBO HASTA QUE SE ESTABLECE CONTACTO CON EL MOLDE, PARA CONSTRUIR LA PARTE DE LA EMBOCADURA, CON SECCIONES ADYACENTES DESTINADAS A LA CONSTITUCION DEL CUELLO. POSTERIORMENTE ES ENFRAIDO Y ES RECONFORMADO EN UN EXTREMO POR CALENTAMIENTO PARA FORMAR EL CIERRE DE LA PIEZA PREMOLDEADA.
