Abstract
LAS PARTES FORMADAS SE FORMAN CON UN POLVO QUE TIENE LA QUIMICA DESEADA DE LA PARTE FINALIZADA, MEZCLANDO EL POLVO CON UNA RESINA DE CONDENSACION TERMOFIJADORA QUE ACTUA COMO ELEMENTO DE UNION. LA RESINA SE PUEDE CATALIZAR PARCIALMENTE, O SE PUEDEN AÑADIR ADITIVOS O AGENTES SUPERFICIACTIVOS PARA MEJORAR LA REOLOGIA, LAS PROPIEDADES DE LA MEZCLA, O EL TIEMPO DE PROCESAMIENTO. AL CALENTARLO, LA MEZCLA DE VISCOSIDAD INHERENTEMENTE BAJA SE SOLIDIFICARA SIN QUE SE LE APLIQUE NINGUNA PRESION. SE OBTIENE UNA FORMA RIGIDA QUE SE PUEDE SEPARAR DE UN MOLDE. LAS FORMAS O PARTES PRESINTERADAS SE REALIZAN POR MEDIO DE UN MOLDE DE INYECCION, UTILIZANDO HERRAMIENTAS SEMIPERMANENTES O PROTOTIPOS. LA RETIRADA DE LOS ELEMENTOS DE UNION SE CONSIGUE POR MEDIOS TERMICOS Y SIN UN PASO SEPARADO DE DESUNION, A PESAR DE LA CONOCIDA RESISTENCIA AL CALOR DE LAS RESINAS TERMOFIJADORAS. LA RETIRADA SE DEBE A LAS CARACTERISTICAS FORMADORAS DE UNA PELICULA DEL ELEMENTO DE UNION, DEJANDO ABIERTOS LOS POROS DE LA PARTE, PROPORCIONANDO CONDICIONES DE OXIDACION DENTRO DE ESTOS POROS A MEDIDA QUE SE CALIENTA LA PARTE, Y ASEGURANDO QUE EL VAPOR QUE DESPIDE LA RESINA SE DIFUNDE A TRAVES DE LOS POROS, CALENTANDO LA PARTE EN UN VACIO.
