Features and Benefits

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, .00157-1.378” (0.040 to 35 mm).

Like all products from Esteves Group, these products are manufactured with the highest quality and accuracy standards.

Polycrystalline diamonds are man-made sintered diamonds and are available in three main groups: self-supported metal filled (designation: Non-supported), tungsten carbide supported metal filled (designation: Supported), and self-supported thermally stable (designation: Thermally Stable).

For each group, several grain structures are available to produce your wire surface finish requirements. All PCD blanks contain randomly oriented diamond particles. The result is a perfectly round wear pattern for each die, ensuring that your wire remains round.
