Abstract:
This method for manufacturing a molded body having a three-dimensional shape includes: a sequential molding step in which, with respect to a metal-containing sheet material having a molding part and a non-molding part around the molding part, the non-molding part of the metal-containing sheet material is held by a jig, and the metal-containing sheet material and a tool arranged on one side of the metal-containing sheet material are moved relative to one another while the tool is pressed against the metal-containing sheet material to sequentially mold the molding part into a three-dimensional shape; a trimming step, carried out after the sequential molding step, in which the non-molding part is trimmed; and a coating film formation step, carried out prior to the sequential molding step and/or the trimming step, in which a resin-containing coating film is formed on at least the side of the metal-containing sheet material on the opposite side from the one side.
