    • PROBLEM TO BE SOLVED: To solve a problem that a tear and a wrinkle occur in a molded product when a metal laminate film as a workpiece is molded by using a mold.SOLUTION: A method for molding a metal laminate film includes: temperature raising steps (S1, S2) of forming both a first enclosed space (6) locally enclosed at an upper surface of a molding part (3a) and a second enclosed space (7) locally enclosed at a lower surface of the molding part (3a) by a punch (2) and a pad (5) facing each other across the molding part (3a) of a metal laminate film (3) as a workpiece, and then compressing the first enclosed space (6) and the second enclosed space (7) to raise a temperature of the molding part (3a) of the metal laminate film (3); an air-compressing molding step (S3) where the molding part (3a) of the metal laminate film (3) is subjected to pressure by the punch (2) and the pad (5) to mold the molding part (3a); and a punch-molding and cooling step (S4) of discharging a gas of the first enclosed space (6) and pressing the molding part (3a) to the pad (5) by the punch (2) for molding and cooling.
    • 要解决的问题:为了解决通过使用模具模制作为工件的金属层叠膜时在模制品中发生撕裂和皱纹的问题。解决方案:一种用于模制金属层压膜的方法包括:升温步骤 (3a)的上表面局部封闭的第一封闭空间(6)和成型部(3a)的下表面局部封闭的第二封闭空间(7)的第一封闭空间(S1,S2) 穿过作为工件的金属层叠膜(3)的模制部件(3a)彼此面对的冲头(2)和垫(5),然后压缩第一封闭空间(6)和第二封闭空间(7) )以提高金属层叠膜(3)的成型部(3a)的温度; 通过冲头(2)和垫(5)对金属层压膜(3)的成型部(3a)施加压力以模制成型部(3a)的空气压缩成型工序(S3) 以及冲压成型和冷却步骤(S4),其排出第一封闭空间(6)的气体,并通过用于模制和冷却的冲头(2)将模制部分(3a)压靠到垫(5)。
