Abstract
Se proporciona un método para preparar un artículo polimérico que incluye introducir una composición polimerizable en un molde; sellar la composición dentro del molde (18) usando un medio de sellado; colocar el molde (18) en un horno de curado por convección (10); someter la composición polimerizable a un ciclo de curado suficiente para curar parcialmente la composición; extraer el molde (18) del horno de curado por convección (10); opcionalmente, retirar los medios de sellado del molde; colocar el molde (18) en una cámara de curado auxiliar (16) que se coloca en el horno de curado por convección (10), o colocar el molde (18) en una cámara de curado auxiliar (16) que se encuentra dentro del horno de curado por convección (10); someter la composición polimerizable a un ciclo de curado adicional para completar la polimerización de la composición, formando así un artículo polimérico curado; y retirar el artículo polimérico curado del molde (18).
