ンを充填されて平面状の下面を有することになる。If the present invention is adopted, it is not necessary to manufacture a conventional mold. A model having a desired shape can be used as a mold. The lower surface of the model, that is, the surface facing the mold base does not need to be a flat surface. The model may be, for example, the shape of an upside down dish, or may be made of a thin metal plate. According to the invention, the model has a planar lower surface, for example filled with polyurethane foam, before being placed on the mold stand.

模型材料の必要条件である。According to the method of the present invention, it is possible to quickly and inexpensively manufacture a prototype part having corresponding characteristics such as a product manufactured by a known method, for example, appearance, insulating ability, rigidity and the like. The method makes it possible to use models with a large shape change range. The cost of the tool is not high since the same flatbed can be used for different shaped models. The model can be made of various materials, such as wood, plywood, sheet metal, or polyester sheet, for example. It is a requirement of the model material that it is not deformed by the hot thermoplastic sheet.

よって凝固されると、型から外される。BEST MODE FOR CARRYING OUT THE INVENTION In the figures, a model 2 is supported by a backing material 1 and placed on a mold table 6 having a flat top surface. A completely flexible and pliable sheet 3 of thermoplastic material heated in a furnace is transferred to the molds (1 and 2). An elastic membrane 4 of pressure bells 5 is applied to press the thermoplastic material tightly against the mold by the pressure in the pressure bells. At the same time, air is discharged from the vicinity of the sheet to be molded through the passage 7. When the sheet 3 is solidified by cooling, it is released from the mold.
0.1MPa以下の圧力が大抵の場合押圧するのに適当であ

Can be best applied to. Of course, it is also possible according to the invention to form reinforced plastic semi-finished products, for example coated with textiles, or semi-finished products constructed by laminating layers of different fiber contents.
