PCD Dies stands for Polycrystalline diamond wire-drawing dies. They can be used in both wet or dry processes. Particularly for larger sizes where wear is more frequent, but the surface finish is not as important,. The longest die life possible, highest production efficiency and lowest downtime. You can find wire in all sizes, from very large to extremely fine. Wire has a predictable surface finish. This is ideal for wire materials that are highly abrasive.
