ND Dies, Natural diamond dies,Fine wire dies

ND Dies, Natural diamond dies usually used as Fine wire dies

Diamond is known as the hardest material in the world, has the extremely high degree of hardness and the good thermal conductivity and the light thermal properties, widely applies in the industrial field in the tool manufacture, in optics product and the conductor profession.

Features:

  • Precise die orientation
  • Accurate die profile
  • Highly polished finish from bell to back relief
  • Accurately sized
  • Straight & consistent reduction angle
  • Maximum wear resistance
  • Minimum die pull
  • Excellent wire surface quality
  • Hole diameters: 0.013 - 1.000mm

Application:

STAR WIRE DIE produces high performance natural diamond dies which are widely used to draw fine wires like magnet wire (normally less than 0.5 mm), tungsten wire and stainless steel wire (less than 0.1 mm).
