Abstract

EL PROCESO SEGUN LA INVENCION ES DEL TIPO SEGUN EL CUAL SE ESTABLECE ANULARMENTE ALREDEDOR DE LAS DOS COQUILLAS DE MOLDEADO (10A, 10B) UN MANGUITO DE CIERRE (14) QUE DEFINE CON ESTAS COQUILLAS DE MOLDEADO (10A, 10B) LA CAVIDAD DE MOLDEADO (15) BUSCADA. SEGUN LA INVENCION, SE ELIGE PARA EL MATERIAL CONSTITUTIVO DEL MANGUITO DE CIERRE (14) UNA MATERIA SINTETICA TERMORRETRACTIL, Y POR UNA OPERACION DE CALENTAMIENTO, SE PROVOCA LA ESTRICCION DE ESTE MANGUITO DE CIERRE (14) SOBRE LAS COQUILLAS DE MOLDEADO (10A, 10B). APLICACION, PARTICULARMENTE EN LOS MOLDES DESTINADOS A LA OBTENCION DE LENTILLAS OFTALMICAS.
