Abstract

SE PUEDEN MEJORAR LOS PASOS DE MOLDES SI, EN LUGAR DE UNA SOLA ABERTURA DE PASO RELATIVAMENTE GRANDE, SE UTILIZA UN PASO QUE TIENE VARIAS ABERTURAS DE PASO RELATIVAMENTE PEQUEÑAS, EN LAS QUE EL AREA DE LA SECCION TRANSVERSAL ACUMULADA DE LAS ABERTURAS DE PASO RELATIVAMENTE PEQUEÑAS ES APROXIMADAMENTE LA MISMA QUE LA ABERTURA DE PASO RELATIVAMENTE GRANDE QUE SUSTITUYEN. TAMBIEN SE HA ENCONTRADO QUE LOS PASOS TIENEN UNA MAYOR CAPACIDAD DE AUTOLIMPIEZA SI LA RELACION DEL FONDO DE LA ABERTURA DE CADA PASO AL DIAMETRO DE LA SECCION TRANSVERSAL DE LA MISMA ES APROXIMADAMENTE 1 O MENOS.
