Due to the vibration of the wire, slight annular wear first occurs in the area that comes into contact with the wire in the compression zone of the drawing die, and then continues to expand until the fixed diameter zone, resulting in a serious decrease in the surface quality of the wire and an expansion of the wire size. Moreover, severe wear can cause transverse cracks (mainly in the drawing process of soft wire) or longitudinal cracks (mainly in the drawing process of hard wire) in the mold, leading to premature scrapping of the mold.

Therefore, it is necessary to scientifically develop maintenance standards for drawing dies based on the type of wire being drawn and the characteristics of drawing. In general, minor circular wear can be restored to use by polishing, or by slightly increasing the diameter to meet the drawing requirements. Excessive wear and tear can significantly reduce the number of mold repairs, even leading to scrapping and an increase in wire drawing costs.

Effective maintenance and repair of wire drawing molds are crucial for reducing costs.
