Polycrystalline Diamond Wire Drawing Dies (PCD)

Polycrystalline diamonds are man-made sintered diamonds. Diamond wire dies with PCD blanks can be used for ferrous and non-ferrous wire drawing applications and for virtually any type of wet and dry wire drawing process. Sizes are available for drawing applications ranging from large drawn rod to ultra-fine wire. This size range includes, but is not limited to 0.030 to 22 mm. 

MN Die supply 4 different kinds of PCD dies to draw different materials, best applications by keeping high quality as well as low cost possible.

We supply semifinished dies and finished dies.

PCD dies are made for all kinds of applications in drawing, compacting, stranding, tube and bar calibrating.
