Wire Drawing Die
Wire drawing dies are accessories used in wire drawing machines to draw metal wire into the desired diameter. Three main materials for wire drawing dies are carbide, natural diamond, and artificial diamond (polycrystalline diamond – PCD).
PCD wire drawing dies and straight line wire drawing machines are a commonly used combination in metal wire drawing processing. Straight-line wire drawing machines provide mechanical support for precise control and efficient production for wire drawing dies to draw metal wires efficiently. PCD wire drawing dies can draw about 300 tons of steel wire, which is widely used in cold drawing of various metal wires such as nail manufacturing, steel wire, stainless steel wire, copper wire, aluminum wire, etc.
PCD wire drawing dies have different sizes, such as 5.8mm, 5.5mm, 5.0mm, 3.7mm, 3.1mm, 2.5mm, etc. You can get any wire diameter using the appropriate wire drawing die size.
Features of PCD Wire Drawing Mold
The service life of polycrystalline diamond wire drawing dies is 4 to 10 times longer than natural diamond dies and 50 to 500 times longer than carbide dies.
Polycrystalline diamond material has excellent wear resistance. The drawing die is not easy to wear during the drawing process and is suitable for mass production.
The wire drawing molds can maintain good die hole roundness, which is very important for ensuring the dimensional accuracy of the drawn wire.
Polycrystalline diamond materials have strong tensile strength, which helps the drawing die to remain stable during high-intensity drawing processes and reduces the risk of breakage or damage.
Although the initial investment in polycrystalline diamond dies may be high, the overall cost of use is relatively low due to its long life and low maintenance requirements.
The hardness of PCD is usually between 80 and 90 HRA, which can effectively cope with the high friction and high pressure generated during metal drawing.
PCD has high thermal conductivity, which helps to dissipate heat during the drawing process effectively and prevents the mold and wire from being damaged due to overheating.
Application of Wire Drawing Die
Wire drawing dies are widely used in metal wire processing, such as steel wire, copper wire, aluminum wire, stainless steel wire, galvanized steel wire, high-strength alloy wire, iron wire, welding wire, etc. Its hardness, wear resistance, and precision ensure production efficiency and product quality. Reasonable selection and maintenance of wire drawing dies can improve production efficiency and reduce costs and are suitable for mass production and high-precision requirements of various metal wire drawing.
