Abstract

PURPOSE:To obtain certainly desired material thickness of a part in a product by a method in which a part of skin material requiring predetermined thickness is pressed to a vacuum forming die by a plug, and at this condition, the plug is caused to follow the movement of the vacuum forming die. CONSTITUTION:The peripheral edge of skin material 1 is heated and softened by a heater. Next, a vacuum forming die 3 is lifted and caused to be in contact with the skin material and pushes the material 1 upwardly. Then a plug 6 is held in a waiting state above the skin material 1. The plug 6 is actuated on the way of lifting of the vacuum forming die 3, and a part of the skin material 1 which needs predetermined thickness, is pushed to the vacuum forming die 3 by the plug 6. Further, the plug 6 is caused to follow the movement of the vacuum forming die 3 at this pushed condition, until the lifting of said die 3 finished.
