On the issue of small inlet angle of wire drawing dies
Due to the fact that the wire first contacts the entrance area of the mold core during the drawing process, the cone angle of the entrance area is small, which not only increases the contact area between the wire and the inner hole, increases the friction force, but also hinders the introduction of lubricants, resulting in poor lubrication effect during the drawing process and seriously affecting the service life of the mold.
The entrance angle of foreign wire drawing die products increases, effectively avoiding scratches between the wire and the drawing die, and introducing more lubricants, enhancing lubrication effect and reducing mold core wear. This change improves the surface quality of the wire and also prolongs the service life of the wire drawing die.
