​​​ND Natural Diamond Wire Drawing Dies

1.  Made from high quality natural diamond
2.  111 orientated and well reinforced
3.  Best die surface finish.
4.  Best quality finish on drawn wire
5.  Size available from 0.015mm to 2.0mm

Abbreviated as ND, are naturally formed within the earth at high-pressure and high-temperature conditions. Because of its extremely rigid lattice, it can be contaminated by a few types of impurities such as boron and nitrogen.

MN offers diamond drawing dies with natural diamond (ND) blanks inside as a high quality and durable product for drawing ferrous and non-ferrous wires .00028-.0787″ (0.007 to 2.00 mm). Smaller and larger sizes are available by request.

Natural diamond can be chosen as a raw material for the following products:

Wire drawing dies
Bunching, Stranding and Compacting dies
Extrusion tools
Burnishing dies

PCD Polycrystalline Diamond Wire Drawing Dies

1. PCD Wire drawing dies are commonly used to reduce the diameter of various ferrous and non-ferrous rods and wires. Applications include high, medium and low voltage cables, automotive, medical wire,superconducting, bonding, and welding wires.

2. MN polycrystalline diamond drawing dies (PCD dies) give the wire manufacturer the ability to maintain uniform wire roundness and minimize material usage.

3. Polycrystalline diamond dies enable a long drawing die life even at high process speeds and high demanding applications.

BENEFITS:

Long lasting (outlasts TC and SSCD/ND dies)
Ideal for long production runs
Ideal for highly abrasive wire materials
Wire remains round, even with significant die wear
Tailored to wire alloy
Tailored to wire requirements (quality wire surface when required)

Applicability and Product Use

PCD dies are frequently used for drawing:

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

Characteristic Technical Specification Parameters Data

COMPAX PCD BLANDS & SUMIDIA WD PCD BLANDS DESCRIPTION

MD Mono Diamond Wire Dies Synthetic single crystal diamonds, also called synthetic mono crystal diamond and abbreviated as SSCD or SMCD or MCD or MD, are man-made diamonds, manufactured under controlled conditions and are free from impurities, inclusions and cracks. These tightly controlled quality aspects lead to predictable and constant die performance.The SSCD blanks that we uses are all <111> oriented with a divergence in the orientation less than 1°.   The result is a close-to-round wear pattern for each die, a quality aspect that previously could only be obtained in small natural diamond dies. KEY FEATURES: Usable with dry and wet draw Available in any casing size Various grain sizes available Dies available for high temperature applications Tight-tolerance dies availableFeatures Polycrystalline diamond can be chosen as a raw material for the following current products: Wire drawing dies Bunching, Stranding and Compacting dies Tubing dies Split dies Shaped wire drawing dies Extrusion tools (both tips and dies) Compacting dies Guide dies Burnishing dies
