In metal press processing. What is caused by an external force to force the metal through the mold, the cross-sectional area of the metal is tightened, and the desired cross-sectional area shape and dimensions are called a wire drawing die.

Drawing die is widely used, such as high-precision wire used in electronic devices, radar, television, exterior and aerospace, as well as commonly used tungsten wire, molybdenum wire, stainless steel wire, wire and cable wire and various alloy wires are drawn by diamond wire drawing die. The diamond drawing die is made of natural diamond as a material, so that it has strong wear resistance and extremely high service life. The production technology of the wire drawing mould sleeve includes several technical steps such as compression molding, drafting and turning.

The wire drawing die is a wire that passes through a mold to make it from coarse to fine, and gradually reaches the scale required by everyone. This special mold is a drawing die. The core of the wire drawing die is usually made of natural diamonds, artificial diamonds (artificial diamonds have GE, PCD, composition, etc.). The copper wire drawing die is attributed to the cord drawing die. There are also hard wire drawing dies, such as pulling tungsten wire. The view point of the copper wire drawing die is usually 16-18 degrees, the sizing length is 30-40%, and the viewing point of the tungsten wire drawing die is relatively small, usually 12-14 degrees, and the length of the line is 60-70. %.

The wire drawing die comprises a diamond wire drawing die, and further comprises a carbide wire drawing die; a plastic wire drawing die and the like. There are many uses.
