Description of the invention: [Technical field to which the invention pertains] - A rapid prototyping method for non-ferrous metal sheets, in particular, a method for manufacturing a casing or a machine member for manufacturing a thinned electronic product. [Prior Art] The application of forging technology has a long history. Although the evolution of forging processing technology has not changed much, the forging has the characteristics of being suitable for mass production, stable dimensional change and suitable for thin parts and material production. Forging technology is still the main process for manufacturing wrenches, heat sinks, and notebook computers. Please refer to the first to third figures. It can be clearly seen from the figure that the conventional forging technique first welds the forged plate of the sheet A to a forged plate B, and then forges the plate 8 and the forged plate B. The sheet A is formed into a final product. However, this is done by pre-welding a forged sheet B on the substrate A, increasing the thickness of the sheet A, and then forging into a final product. Or as shown in the fourth to sixth figures, the thicker sheet is subjected to multiple punching to form the desired size of the final product. • However, the above problems still have the following problems: 1. The forged plate B is welded to the plate A by welding, and the working time required for welding is very long, and if the forged plate B is unsold or the welding is incomplete, it is easy to be in the forging process. The separation of the sheet A in the middle causes an increase in the defective rate of the product. In addition, the use of the welding method is equivalent to adding a project number in the process, which is equivalent to increasing the working hours and manufacturing costs. 2. The shape of the sheet A cannot be close to the appearance of the final product. To achieve the final size, multiple forgings are required to form the final product. This conventional technique requires multiple sets of molds 5 1332869 and working hours to make the product manufacture. Increased costs and low production capacity. Therefore, it is the subject of the improvement of sulfur in the industry. SUMMARY OF THE INVENTION The main object of the present invention is to make the non-metallic sheet to be forged, which is the size of the most suitable product, and to forge into the final product. This way, the forging method can be reduced, the problem of forging needles can be reduced, and the product yield can be effectively increased and the production capacity can be increased. [Embodiment] In order to make the technical content and principle of the present invention easy to understand, the following embodiments can be made in accordance with the specific embodiments, but the scale of the present invention is simplistic, and those skilled in the art can easily understand the contents disclosed in the present specification. The present invention may be embodied or modified by other specific embodiments, and various modifications and changes may be made without departing from the spirit and scope of the invention. Referring to the fourth to sixth figures, the rapid prototyping method disclosed in the present invention can be understood from the following, which is a method for forming a non-ferrous metal sheet 1 by stamping or bending. If the forging is bent out of the folded edge 1 i, the folded edge 11 is formed to a sufficient thickness to make the outer shape of the sheet 1 close to the appearance of the final product, and then the forging technique is used to forge the sheet 1 into a final product. The rapid prototyping method of the non-ferrous metal plate disclosed in the present invention can be applied to the outer casing of a thin electronic product, for example, a mobile communication device, a notebook computer, a liquid crystal display device, a frame group used in a backlight module, and 6 1332869 Cold forging or hot forging in the forging technique can be applied to the method disclosed in the present invention. In addition, the fresh iron metal plate may be a light metal, for example, a wire alloy base alloy. The main feature of the method disclosed by the present invention is that the final product is an integral type and the number of projects is reduced. Compared with the need to use welding engineering, or multiple sets of mold forging can be the most wealthy learning age, this (4) way because the product is - body forming, it can save materials, increase product strength, reduce the number of projects, reduce costs, work Time to reduce, increase and increase product yield. therefore,
