An method of manufacturing a hot press-formed member comprises heating a blank of an aluminum-based plated steel sheet in a heating furnace, removing the heated blank from the heating furnace and conveying the removed blank between an upper mold portion and a lower mold portion of a mold, mounted on a press, to be seated; and performing a forming process after the upper mold portion of the mold is in contact with the seated blank. Un método para manufacturar un miembro formado en prensa caliente comprende calentar una preforma de una lámina de acero chapada a base de aluminio en un horno de calentamiento, remover la preforma calentada del horno de calentamiento y transportar la preforma removida entre una porción de molde superior y una porción de molde inferior de un molde, montada sobre una prensa, para ser asentada; y realizar un proceso de formación después de que la porción de molde superior del molde está en contacto con la preforma asentada.
