PROBLEM TO BE SOLVED: To prevent a breakage at a drawn portion or a wrinkle except the portion by partly warming a skin material set to a mold by a heating means before clamping the mold in a method for lamination molding having the steps of interposing the material between a pair of molds and then injection casting a molten resin in a mold cavity space. SOLUTION: In the case of lamination molding to obtain a molding by fusion adhering to integrate a surface of a core material with a skin material W, a skin material S is set to a surface of a movable mold 4 opposed to a fixed mold 3 in the state that both molds 3 and 4 of a molding apparatus are opened. Then, an elevation means 15 is driven to move to descend a vertical shaft 15a, a heat ray heater 13 and a baffle plate 14 are positioned and holed at a position opposed to the material S, and then a heat ray is radiated from the heater 13 to partly warm the material S in a range for passing the opening 14a. Thereafter, the shaft 15a is moved to be raised. The molds 3, 4 are clamped in the state that the heater 13 and the plate 14 are disposed and held above both the molds 3, 4, and a molten resin to become the core material is injection cast and dwell loaded.
