Diamond dies - Polycrystalline diamond wire dies (PCD dies)

Features

Esteves Group is a manufacturer of diamond wire dies with polycrystalline diamond (PCD) blanks that can be used for ferrous and non-ferrous wire drawing applications. Sizes are available for drawing applications ranging from ultra-fine wire to large drawn rod. This size range includes, but is not limited to, 0.040 to 35 mm (.00157 - 1.378").

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

Polycrystalline diamonds, abbreviated as PCD, are man-made sintered diamonds and can be used for almost any type of wet or dry wire drawing application and are available in three main groups: unsupported and supported metal filled, and thermally stable.

For each group, several PCD blanks are available that match your wire surface finish needs as they are offered in diamond grain sizes ranging from 1 to 50 microns.

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.

Let our experienced sales staff help you choose the most cost-effective or readily available diamond blank for your application or let us know if you specifically need a Sumitomo-Sumidia or Diamond Innovations-Compax PCD blank.

 

Key benefits of Esteves Group PCD diamond wire dies

Available for almost any type of wire drawing operation, from rod-size to fine-size
Can be used for wet and dry drawing applications
Predictable wire surface quality
Contain randomly oriented diamond crystals, making certain that wire remains round; even with significant wear the wire remains round
Blank dimensions are guaranteed, hence maximum recut dimensions can be predicted

 

Applicability

Polycrystalline diamond blanks as a base material can be successfully applied in almost any wire drawing operation, from rod-size to intermediate and fine size wires.

The randomly oriented sintered diamond crystal structure makes these nib types stay round during use and its longevity is known to outperform both natural and synthetic single crystal diamond dies.

Typical application areas:
Copper wire
Aluminum wire
Tungsten wire
Molybdenum wire
Stainless steel wire
Coated steel wire
Special alloy and high performance alloy wire
Precious metal wire
Various other ferrous and non-ferrous metal wire types
