Wire Drawing Die

Wire Drawing Die: The Key Component of the Wire Drawing Machine

The wire drawing die is an essential accessory in the wire drawing machine for drawing metal wire into the required diameter. It is widely used to draw various metal wires such as steel wire, copper wire, aluminum wire, stainless steel wire, galvanized steel wire, alloy wire, iron wire, and welding wire. Its internal structure consists of gradually decreasing aperture, and the metal wire is drawn to the required diameter under the tension traction of the wire drawing machine.

To ensure a smooth drawing process, lubricants such as wire drawing powder are usually used to reduce friction, prevent drawing die wear, and improve the surface finish of the wire. The lubrication quality directly affects the wire’s final quality and the drawing die’s service life. Therefore, choosing the proper drawing die and the correct lubrication method is essential for the efficient production of metal wire.

Materials of Wire Drawing Dies

The main materials of drawing dies include tungsten carbide (TC) wire drawing dies, natural diamonds (ND), and polycrystalline diamond (PCD) wire drawing dies. Each material has unique advantages and is suitable for different wire drawing processes and wire types.

PCD Drawing Dies

In metal wire drawing, PCD wire drawing dies are the most common and practical choice for straight-line wire drawing machines. With its excellent wear resistance, PCD drawing dies can produce about 300 tons of cold-drawn wire under normal usage circumstances, which makes it an ideal choice for the production of a variety of metal wires such as nail manufacturing, steel wire, copper wire, aluminum wire, stainless steel wire, etc. PCD drawing dies are available in various sizes, such as 5.8mm, 5.5mm, 5.0mm, 4.7mm, 4.1mm, 3.4mm, 2.8mm, 2.5mm and 2.0mm. Choosing the right wire drawing die size can obtain the required wire diameter to meet different production needs.
