Abstract
PROCEDIMIENTO Y DISPOSITIVO PARA MOLDEO POR EXTRUSION DE PERFILES HUECOS DE MATERIALES POLIMEROS CON PARED COMPUESTA. LOS OBJETOS FABRICADOS TIENEN UNA PARED CON UNA ZONA EXTERIOR COMPACTA DE POLIMERO, UNA ZONA CENTRAL DE POLIMERO ESTRUCTURADO DIFERENTE Y UNA PARED INTERIOR COMPACTA DE POLIMERO. EL MATERIAL POLIMERO COMPACTO DE LA PARED INTERIOR SE ALIMENTA, YA EN LA ZONA CILINDRICA DELANTERA DEL UTIL, A LA COMBINACION PARED EXTERIOR-ZONA CENTRAL TRANSPORTADA CONJUNTAMENTE SOBRE UN MANDRIL. EL MATERIAL POLIMERO COMPACTO DE LA PARED INTERIOR SE CONECTA CON LA PERIFERIA INTERIOR DE LA ZONA CENTRAL DE LA PARED EN ESTE LUGAR MEDIANTE SOLDADURA POR EXTRUSION. EN EL DISPOSITIVO LAS NERVADURAS DE RETENCION (83) DEL MANDRIL (8) Y LAS NERVADURAS DE RETENCION (94) DEL MANDRIL INTERIOR (21) SE DISPONEN DESPLAZADAMENTE ENTRE SI.
