Abstract
UN METODO PARA FABRICAR UN ELEMENTO DE INSERCION DE MOLDE ESFERICO CONCAVO POR ELECTROPLASTIA DE NIQUEL SOBRE UN REVESTIMIENTO DE AGENTE DE LIBERACION DE PLATA SOBRE UNA SUPERFICIE ESFERICA FORMADA EN UN SUSTRATO DE COBRE PARA FORMAR UN MAESTRO QUE TIENE UNA SUPERFICIE CONVEXA QUE ES UNA IMAGEN NEGATIVA DE LA SUPERFICIE ESFERICA. DESPUES DE QUE SE HA SEPARADO EL MAESTRO DEL SUSTRATO SU SUPERFICIE CONVEXA SE REVISTE CON UN AGENTE DE LIBERACION DE PLATA Y SE ELECTROGALVANIZA CON NIQUEL PARA FORMAR UN ELEMENTO QUE TIENE UNA SUPERFICIE CONCAVA QUE ES UNA REPLICA DE LA SUPERFICIE ESFERICA Y LA SUPERFICIE OPUESTA DE ESTA ES CONVEXA. DESPUES DE QUE LA SUPERFICIE CONVEXA DEL ELEMENTO HAYA SIDO ACONDICIONADA EN FORMA ESFERICA SE FORMA UN SEGMENTO EN D ESFERICO LIGERAMENTE SOBREDIMENSINADO EN LA SUPERFICIE ESFERICA. LA SUPERFICIE ESFERICA SE ACONDICIONA ENTONCES PARA REDUCIR EL SEGMENTO EN D EN SU DIMENSION FINAL PARA PRODUCIR EL ELEMENTO DE INSERCION. SE FORMA UN NUMERO DE ELEMENTOS A PARTIR DEL PATRON Y ESTAN PROVISTO DE SEGMENTOS EN D DE DIFERENTES RADIOS. EN UN METODO ALTERNATIVO EL SEGMENTO EN D SE FORMA EN LA SUPERFICIE CONCAVA ESFERICA DE UN SUSTRATO DE VIDRIO, LA SUPERFICIE CONCAVA ESFERICA DE ESTE TIENE LA MEJOR ADAPTACION A LA SUPERFICIE ESFERICA DESEADA.
