PURPOSE:To allow no leak of a foaming material, by a method wherein in monolithic molding of a skin material and pad material the skin material is set up to a molding tool by providing a magnetic material to a mating part of the terminals of the skin material. CONSTITUTION:A permanent magnet 5 is buried in a startionary mold 2 of a molding tool 1. A skin material Wa to which a urethane sheet Y is stuck is set up to a molding surface 2a by breaking a movable mold 3 from a stationary mold 2. In this instance, a mating part Wb of terminal parts of the skin material Wa is faced to the permanent magnet 5. When the movable mold 3 is clamped with the stationary mold 2, the urethane sheet Y is attracted strongly to the permanent magnet 5 and the mating part Wb of the terminals of the skin material Wa is stuck closely with each other. The inside of a bag of the skin materials Wa is filled with foamable urethane resin which is a pad material Wc and foamed under this state. In this instance, as the mating part Wb of the terminals is stuck firmly by the permanent magnet 5, a leak of the foamable urethane resin is prevented. |
