General Information about wire drawing tool.

Die is a round-shaped tool, that designed for narrowing a large diameter of copper or aluminum workpiece. Drawing tool (die) has the special channel configuration that facilitates the stretching process.

The required wire diameter is obtained by multiple drawing process with the gradual decrease of the hole diameter. It is used from 9 to 27 drawing stages and tools.

PCD polycrystal - has a characteristic dark color. This is the artificial diamond, that created by using small diamond particles and metal powder? which was pressed under high temperature into the single substance.

Dies,which made of polycrystalline diamond, have a long service life, allow to obtain a wire with excellent roundness, and also make it possible to predict dies wear period.

Q&A

What is a drawing tool?

Drawing tool (the alternate name is die) is a round-shaped tool, that designed for narrowing a large diameter of copper or aluminum workpiece. Drawing tool (die) has the special channel configuration that facilitates the stretching process. By repeatedly a workpiece stretching with a gradually decreasing diameter of the outlet, it is obtained the required diameter of wire.

What characteristics of the drawing tool (die) are important when choosing it for wire manufacturing?

Important characteristics of drawing tool include:

  • Shape and size of holes;
  • Length;
  • Wear resistance;
  • Surface quality;
  • Diameter accuracy
What materials are most often used for the drawing tool (die) manufacturing?

The drawing tool (die) are made of carbide materials, such as tungsten carbide. The central insert is made of a industrial diamond, that has a darkish color. This combination of materials makes the drawing tool (die) sufficiently wear-resistant and durable, and it significantly increases the production life of the tool.
