摘要： A method of forming a part includes: inserting a blank into a die, the die comprising a mold mounted above a sealing counterpart; clamping the blank between the mold and the sealing counterpart; applying first pressure on the blank from the sealing counterpart so the blank is pressed upward to form a shaped part corresponding to the mold; applying a vacuum to the shaped part to hold it against the mold also after separating the mold and the sealing counterpart, the vacuum applied through at least one opening in the mold located in a corner of the mold that the blank does not reach when the first pressure is applied; and discontinuing the vacuum to allow the shaped part to be released from the mold.
