Abstract

CUERPOS METALICOS SINTERIZADOS (1, 3) DE GRAN SECCION, QUE EN DETERMINADAS ZONAS DE SU SUPERFICIE O DE SU SECCION ESTAN SOMETIDOS A CARGAS MUY ELEVADAS, COMO LAS HERRAMIENTAS PARA MOLDEO POR PRESION, RESISTEN ESTOS ESFUERZOS MEJOR CUANDO SE SINTERIZAN BAJO CONDICIONES OPTIMIZADAS, EN LOS CUALES DE ACUERDO CON LA INVENCION, EN EL PRENSADO O DESPUES DE EL Y ANTES DEL SINTERIZADO, SE PROVEEN CON CANALES U ORIFICIOS (8), QUE HACEN POSIBLE UNA MEJOR EVAPORACION DEL AGLUTINANTE, UN MEJOR INTERCAMBIO DE GAS Y UNA MEJOR EVACUACION, PARA LO CUAL LOS CANALES U ORIFICIOS (8) ESTAN CONDUCIDOS DESDE LAS ZONAS DE LA SUPERFICIE MENOS CARGADAS EN USO A TRAVES DE LAS ZONAS DE LA SECCION MENOS CARGADAS.
