Abstract
SE LLEVA A CABO UN PROCESO DE FUNDICION CON LA FORMACION DE UN MODELO VACIO EN UN PATRON VACIO Y SU RECUBRIMIENTO CERAMICO UNA VEZ FORMADO. EL PROCESO COMPRENDE LOS PASOS SIGUIENTES: 1) FABRICACION DE UN MODELO POSITIVO (ES DECIR, CON LA MISMA FORMA QUE LA PIEZA DE FUNDICION A REALIZAR) CON MATERIAL RIGIDO O ELASTICO, SEGUN LOS CASOS. 2) FABRICACION DE UN PATRON TEMPORAL VERTIENDO UN LIQUIDO SOBRE EL MODELO POSITIVO Y ENFRIANDOLO HASTA SU SOLIDIFICACION. 3) EXTRACCION DEL MODELO POSITIVO. 4) FORMACION DE UN MODELO TEMPORAL VERTIENDO UN SEGUNDO LIQUIDO EN LA CAVIDAD DEL PATRON TEMPORAL Y ENFRIANDOLO HASTA SU SOLIDIFICACION. 5) FUNDICION O SOLUCION DEL PATRON TEMPORAL. 6) RECUBRIMIENTO DEL MODELO TEMPORAL CON CERAMICA, FORMANDO UN REVESTIMIENTO CERAMICO SOLIDO ALREDEDOR DEL MODELO TEMPORAL. 7) FUNDICION O SOLUCION DEL MODELO TEMPORAL Y EVACUACION DEL LIQUIDO RESULTANTE DEL RECUBRIMIENTO CERAMICO. 8) RELLENO DE LA CAVIDAD DE RECUBRIMIENTO CON METAL FUNDIDO AL QUE SE PERMITE SOLIDIFICAR PARA FORMAR LA PIEZA DE FUNDICION FINAL. EL PROCESO PERMITE PRODUCIR TODOS LOS TIPOS DE PIEZAS DE FUNDICION DE ALTA CALIDAD Y POSIBILITA, A PESAR DE SU COMPLEJIDAD, FORMAR UN MODELO VACIO, EVITANDO EL RIESGO DE ROTURA DE MODELOS VACIOS Y LA NECESIDAD DE USAR NUCLEOS (CON RIESGOS ELEVADOS DE DEFORMACION). ADEMAS EN LA PRODUCCION DE LOS MODELOS Y PATRONES VACIOS SE USAN MATERIALES RECICLABLES.
