Field of the Invention The present invention relates to a method of manufacturing a spiral rotor of a compressor, and more particularly to a method of manufacturing a compression rotor which can reduce manufacturing cost and loss of a cutting tool and a tool. [Prior Art] The spiral rotor of a general compressor is mostly made of a piece of metal, which is cut by a processing machine to form a spiral main body structure, at the end of the - screw and spiral body structure. It is also necessary to cut the shaft for the pivoting end, and the other end needs to cut the shaft connected to the driving motor. The above-mentioned manufacturing method of Renqi must cut off the multi-metal material before the spiral rotor is formed, resulting in waste of the metal material. In addition, the processing machine and the cutting knives and tools used are expensive, and after such a large number of cutting operations It is easy to cause damage to the cutting tool and tool, which will increase the manufacturing cost and reduce the service life of the cutting tool and tool. SUMMARY OF THE INVENTION The present inventors have made research and development in view of the shortcomings of the conventional spiral rotor described above, in order to improve the above-mentioned conventional problems, and have finally developed the present invention through continuous experimentation and efforts. The main object of the present invention is to provide a method for manufacturing a compressor spiral rotor which can reduce the manufacturing cost and the loss of the cutting tool and the tool material. In order to achieve the above objects, the present invention has been achieved by the following technical means, which include:

The second half of the finished product does not need to be processed later, so the second half of the finished product can be formed. Reducing the metal material and the lathe can reduce the cost and reduce the loss of the workpiece of the processing machine. In the accommodating part of the mold, the liquid metal in the scale may contain some impurities in the flooding, and float up and accumulate toward the upper side of the mold. Therefore, if the mold is slightly larger, the impurities will accumulate in the accommodating portion. Second, the younger brother - the part that he wants to cut, and the process step in the processing step, so this (4) can also ensure that the material of the spiral rotor itself is removed [simplified illustration], the first picture The second figure is a schematic diagram of the state of the first mold produced by the present invention.
