During the drawing process, the steel wire is heated due to deformation heat and frictional heat, especially during continuous drawing. Choose the fit diamond die 

(Co Bond PCD  die or Silicon Bond PCD die) is important. LINKUT with richful experience for pcd the wire drawing tools.

1) The larger the working cone angle of the mold, the greater the drawing force generated when the wire is drawn. The shorter the contact length between the wire 

and the mold, the more severe the deformation, and the more heat is released per unit time when the wire is deformed. Finally, the temperature of the steel wire is 

higher when it exits the mold, which causes the steel wire to increase in tensile strength and hardness, and reduce the bend and the torsion value.

2) The longer the die bearing zone, the smaller the elastic aging after the wire is drawn, the better the bearing effect, but as the bearing zone grows, the friction between 

the steel wire and the mold increases, which intensifies wear and causes When the drawing force increases, the temperature of the steel wire also increases at this time, 

resulting in an increase in tensile strength and hardness, and a decrease in bending and torsion values. 

3) During the drawing of medium and high carbon steel, as the drawing temperature increases, the aging mechanism is accelerated. As a result, the plasticity of the 

steel wire decreases, the tensile strength increases, and the torsion value decreases.
