[0003] For a long time, the processing methods of metal perfume bottle caps have been mainly through turning, that is, the cylindrical blank is processed into the shape of the perfume bottle cap through a lathe, and the second is through precise mold making, the metal is melted and injected into the mold to form the initial shape of the bottle cap, and then the fine processing technology takes over, through a series of operations such as turning, grinding and polishing, the surface of the bottle cap is made as smooth as a mirror.

[0004] The traditional turning method starts with a cylindrical blank and forms the desired bottle cap shape by removing a large amount of material. This method leads to a large waste of raw materials and increases costs. Due to the large tool wear during the turning process and the unevenness of the material, it is difficult to ensure that the size and shape of each perfume bottle cap are exactly the same. This difference may affect the quality of the final product. By melting the metal and injecting it into the mold to form the initial shape of the bottle cap, defects such as pores and shrinkage holes will appear, resulting in low strength, poor mechanical properties, and surface defects of the bottle cap, resulting in a low yield rate of the processed bottle cap.

[0005] The cold forging process is a method of placing metal into the mold cavity at room temperature, performing plastic processing on the metal blank under strong pressure and a certain speed, forcing the metal to take shape in the mold cavity, and thus obtaining the required part size and shape.
