Abstract
SE DESCRIBE UN PRODUCTO SEMITERMINADO (5) HECHO DE MATERIAL ELASTOMERICO EN BRUTO QUE SE SEMIVULCANIZA EN UNA CAMARA DE SEMIVULCANIZADO (4) DEFINIDA ENTRE DOS MEDIO-MOLDES (2,3) DISPUESTOS UNO CERCA DEL OTRO. EN EL MOLDE (1A) SE CREA LA MISMA PRESION QUE LA GENERADA POR GASES EN EL PRODUCTO. LOS MEDIO-MOLDES SE SEPARAN Y LA PRESION EN EL MOLDE SE REDUCE GRADUALMENTE, Y SE INCREMENTA LA EXPANSION Y CONSECUENTE TRANSFERENCIA DEL PRODUCTO DESDE LA CAMARA (4) HASTA LA CAMARA DE VULCANIZACION FINAL QUE LA RODEA (6). CUANDO EL DIAMETRO INTERNO DEL PRODUCTO ES MAYOR QUE EL DE LA CAMARA DE VULCANIZADO (6) ESTA SE CIERRA EN SU BORDE CIRCUNFERENCIAL INTERNO, TRAS EL POSIBLE INCREMENTO DE LA PRESION EN EL MOLDE, EN SU BORDE CIRCUNFERENCIAL EXTERNO, PARA ENCERRAR INTEGRAMENTE EL PRODUCTO Y PERMITE COMPLETAR EL PROCESO DE VULCANIZACION.
