The processing quality of PCD Wire Drawing Die Tool is directly related to the degree of the die wear.

1) The assembling of the drawing pcd die blank and the case is asymmetrical: the uneven distribution of the inlaid hard alloy case or there are voids, which  easily lead to U-shaped

cracks in the process of drawing the wire;

2) In the process of laser drilling of diamond die blanks, sintering marks are not cleaned or heated unevenly, which will cause metal catalysts, binders, etc. in the diamond layer to gather

together, which will easily cause pits in the mold during the drawing process;

3) The die core shape design is unreasonable: the opening of the inlet lubrication area is too small, and the bearing area is too long, which will lead to poor lubrication, causing the mold 

to wear or even crack.
