Abstract

LA INVENCION CONCIERNE A UN PROCEDIMIENTO PARA LA FABRICACION DE PERFILES A PARTIR DE MATERIALES POLIMEROS FUNDIDOS EN LA VIA DE LA EXTRUSION. PARA ELLO, ANTES DE DAR FORMA EN LA CORRIENTE DE FUNDICION DEL PRIMER MATERIAL POLIMERO SE INTRODUCE EN LA DIRECCION DE LA CORRIENTE DE FUNDICION UN SEGUNDO MATERIAL POLIMERO. DESPUES SE CONFORMAN LAS CORRIENTES DE FUNDICION POR MEDIO DE UNA HERRAMIENTA DE EXTRUSION EN UN PERFIL, DESPUES DEL ENFRIAMIENTO SE CORTA Y SE RETIRA. LA INVENCION CONSISTE EN QUE LA DILATACION DEL SEGUNDO MATERIAL POLIMERO SE PUEDE VARIAR EN LA CORRIENTE DE FUNDICION DEL PRIMER MATERIAL POLIMERO. LA VARIACION TIENE LUGAR MEDIANTE LA SEPARACION DEL PUNTO DE INYECCION DEL SEGUNDO MATERIAL POLIMERO DE LA ENTRADA DE LAS CORRIENTES UNIDAS DE FUNDICION EN LA HERRAMIENTA DE EXTRUSION. OTRA POSIBILIDAD DE INFLUENCIA LA OFRECE LA VARIACION DE LAS DIMENSIONES DE LA SECCION DEL ORIFICIO DE INYECCION PARA EL SEGUNDO MATERIAL POLIMERO.
