The forming process of cut-resistant tungsten wire does require special equipment. These equipment are specially designed to ensure that the tungsten wire can achieve the desired shape, size and performance during the forming process.
First, in the raw material processing stage, although some basic screening and mixing equipment may be similar to other powder metallurgy processes, higher precision screening machines and mixers may be required to ensure the uniformity and purity of the raw materials for the special properties of tungsten powder (such as high melting point, high density, etc.).
Secondly, in the forming stage, the press is an indispensable equipment. Since the tungsten wire needs to have a high density and uniformity, the press needs to have sufficient pressing force and stability to ensure that the blank can form a tight and uniform structure during the pressing process. In addition, the design and manufacture of the mold is also crucial, because the shape and size of the mold will directly affect the shape and size of the final tungsten wire.
In the sintering stage, the sintering furnace is the core equipment. The sintering furnace needs to be able to accurately control the temperature and time to ensure that the tungsten blank can undergo sufficient densification and grain growth during the sintering process, while avoiding adverse conditions such as overburning or underburning.
Finally, in the wire drawing stage, the wire drawing machine is the key equipment for producing cut-resistant tungsten wire. The wire drawing machine needs to have a stable drawing speed and processing rate control system, as well as a good lubrication and cooling system to ensure that the drawn tungsten wire has a uniform diameter, a smooth surface, and meets the requirements of cut resistance.
