Abstract

SE TRATA DE UN PROCEDIMIENTO SIGUIENDO EL CUAL, PARTIENDO DE UN TEJO DE MATERIAL SINTETICO (10), SE DISPONE ESTE TEJO (10) HORIZONTALMENTE EN UN MOLDE (11) CON SUPERFICIES DE MOLDEO (12S, 121) OPTICAMENTE ACABADAS Y SE LE SOMETE EN CALIENTE A UNA CARGA DE MOLDEO DETERMINADA. SIGUIENDO LA INVENCION, SE ELIGE PARA MOLDE (11) UNO CUYA SUPERFICIE DE MOLDEO SUPERIOR (12S) PERTENECE A UNA COQUILLA (13S) MONTADA LIBREMENTE COLINDANTE EN UN MANGUITO (14), SE LIMITA LA CARGA DE MOLDEO A LA CARGA ESTATICA QUE RESULTA DEL PESO DE ESTA COQUILLA (13S), EVENTUALMENTE AUMENTADA EN EL PESO DE UNA MASA DE PRECARGA ENCIMA DE ESTA, Y SE COLOCA JUNTO EN UN HORNO. APLICACION, EN ESPECIAL, A LA OBTENCION DE LENTILLAS OFTALMICAS DE POLICARBONATO.
