Why are people still using ND dies even at the double cost?
Wire drawing is a metalworking process used to reduce the cross-section of a wire by pulling the wire through a single, or series of, drawing dies. There are many applications for wire drawing, including high, medium and low voltage cables, automotive, medical wire, superconducting, bonding, and welding wires. Although similar in process, drawing is different from extrusion, because in drawing the wire is pulled, rather than pushed, through the die. Drawing is usually performed at room temperature, thus classified as a cold working process, but it may be performed at elevated temperatures for large wires to reduce forces. The wire dies we could supply are TC drawing dies, PCD wire drawing dies, Nano drawing dies, ND dies and other Customized Dies.
ND dies also named Natural monocrystalline diamond dies, which is the hardest known material, almost twice as hard as cubic boron nitride. Approximately 6% of the rough natural diamond is suitable for the production of drawing die.
The diamonds are thoroughly inspected before they are flattened, then they are inserted in a stainless steel case that is later mounted by a heating process. Our diamond dies are widely accepted for fine wire drawing.
ND dies enable long drawing die life with long-lasting dimensional tolerances, even for highly demanding applications. Our ND drawing dies are manufactured with a mirror polish and a smooth wire entry to ensure optimal die life and string-up.
Standard Casing Size for ND Dies are 25mm x 8mm or 25mm x 10mm, diamond dies from a size range of 0.050mm to 1.000mm.
Application:
The natural diamond die is mainly used for drawing with fine wire and ultra-fine wire, or it is widely used in applications requiring excellent wire surface finish and good heat dissipation performance.
- Tungsten wire.
- Semiconductor alloy wire (gold wire, copper wire, silver plated copper wire, aluminum wire, silver alloy wire, etc.)
- Stainless steel wire (304 wire, 316L wire, 430 wire, 201 wire, 202 wire, etc.)
- Copper wire (pure copper wire, silver copper alloy wire, aluminum copper alloy wire, brass wire, copper clad aluminum wire, etc.)
- Steel wire (Saw steel wire, spring steel wire, tire copper plated steel wire.)
- Precious metal wire
- Special alloy wire (copper-nickel alloy wire, nickel-chromium alloy wire.)
Advantage:
- Natural diamond is the best material with the best surface finish among all mold core materials
- The extremely high hardness and wear resistance ensure the service life of the mold
- Natural diamond has the highest thermal conductivity among all mold core materials and can be used for high-temperature processing
- Natural diamonds can withstand temperatures up to 1700 ℃
- Easy debugging, smooth wire drawing process
Now you should know why people continue to use ND dies, even though it is not the economical and practical wire drawing tool that they finally seek.
