Wire Drawing Dies: Crucial information to know


There are different types of tools and equipment that industries are required to use to enhance their production efficiency. One such tool is the Wire Drawing Dies. These are considered to be tools that come with specifically shaped holes via which the wire is drawn for reducing its diameter and is highly polished. They also are fitted with metal case along with a nib that is constructed from the following:

  • Natural diamond
  • PCD (polycrystalline diamond)
  • TC (tungsten carbide)


While choosing diamond drawing dies, it is essential to take into consideration several parameters like wire drawing and material to use. Generally, wire materials tend to include the following:

  • Stainless steel
  • Copper
  • Tungsten
  • Aluminium alloy steel
  • Gold
  • Galvanized high carbon steel
  • Stainless steel
  • Silver
  • Molybdenum
  • Low carbon steel
  • nickel

Trying to draw the parameters is likely to include the following measurements like bell radius, inlet diameter, approach angle, entrance angle, back relief and bearing. Another crucial consideration to make at the time of selecting nano dies is elongation along with ratio of length on drawing to length before drawing.

Know the types

For this type of tool, there are readily available various types to choose. Some of the examples include PCD, standard, enamelling and TC dies. The standard type is said to come with a clearly defined reduction angle to reduce the drawing forces. It also offers uniform de-formation along with consistent surface finish. On the other hand, the PCD type makes use of PCD (polycrystalline diamond). This synthetic material assures to offer the tool with superior resistance from general wear and tear and cracking.  TC dies are manufactured using tungsten carbide. They are made from scratch resistant and extremely hard material often used for tool bits. The Tungsten carbide dies are generally used for drawing thicker wires. It is also used in those applications where using PCD Dies are found to be extremely expensive or not viable. Enamelling dies are used along with enamelled wires. They feature internal geometries that suit tiny wire sizes easily. For more details on the different types of wire dies, go through the website https://www.szwiredie.com/!


Wire dies are generally used along with different types of wire drawing equipment and tools. Pull-in dogs are said to be used for having a better grip over the wire’s ends at the place where it enters the die. Once the pull-in dog gets fastened to the overall block, next a wire is drawn via the die. PCD Drawing Dies and wire dies are used with multiple block and single block machines with ease. Wire in the single block equipment is passed through the die to collect on the standard block. Wires in the multiple block machines are pulled via a die, wrapping around the block that is slightly tapered. The wire moves onto the collector pins located upwards before exiting upper section, thereby reducing back tension. Gravity blocks or Inverted drawing machines are typically used along with coarse wire sizes. It is also used for drawing wires desiring superior surface quality. Reputed suppliers can offer top quality PCD Wire Drawing Dies for such machines.
