There are generally several ways to solve the problem of wire drawing die: a, to improve the local smoothness and hardness of the die that is easy to be drawn, surface quenching, titanium plating, carburizing and nitriding can be adopted; B, improve the maintenance frequency of molds, and focus on polishing this part; C, focus on cooling local areas, such as increasing the spraying amount of release agent and local water cooling; D, reducing the casting temperature; E, appropriately increase the iron content in the alloy.
