Introduction to Wire Drawing Dies Application Wire Range

Posted by Locke Liu on April 20th, 2019

In various industries, such as high-precision wire materials used in electronic devices, radar, television, instrumentation and aerospace, as well as commonly used tungsten wire, molybdenum wire, stainless steel wire, wire and cable wire and various alloy wires are drawn out by diamond wire drawing dies. The diamond wire drawing die has strong wear resistance and high service life due to the use of natural diamond as a raw material.

In metal press working, a tool that forces a metal through a die under an external force, a metal cross-sectional area is compressed, and a desired cross-sectional area shape and size is obtained, which is called a wire drawing die. The wire drawing die is a wire that passes through a mold to make it from coarse to fine and gradually reaches the size required by people. This special mold is a drawing die.

The core of the wire drawing die is generally made of natural diamond, synthetic diamond polycrystalline (PCD, CD composite, etc.). The copper wire drawing die belongs to a soft wire drawing die. There are also hard wire drawing dies, such as pulling tungsten wire. The angle of the compression zone of the copper wire drawing die is generally 16 degrees -18 degrees, and the sizing length is 30%-40%. The angle of the compression zone of the tungsten wire drawing die is relatively small, generally between 12 degrees and 14 degrees, and the length of the row is 60%-70%.
