Drawing Method Graphite Mold

Drawing method graphite mold play an important role in the wire drawing process.

Wire drawing is a modern metal wire processing technology. The graphite mold is mainly used to control the precision forming process of metal wires through plastic deformation to achieve the required diameter. During the entire wire drawing process, the graphite mold achieves high-precision drawing of various metal wires such as copper, aluminum, and steel by virtue of its unique properties. The channels in the die allow the metal wire to undergo progressive deformation when passing through, thereby obtaining finished wires with high surface finish and excellent dimensional consistency.
Compared with traditional die materials such as cemented carbide and polycrystalline diamond, graphite dies have shown excellent performance in many aspects in the wire drawing process, such as
1. Self-lubricating properties: Graphite molds have natural lubricity, which can greatly reduce the friction coefficient between the metal wire and the die wall during use, reduce energy loss and surface scratches, and reduce the amount of lubricant. This feature is particularly prominent in high-speed wire drawing.

2. Excellent thermal conductivity: Graphite has high thermal conductivity, which can quickly dissipate friction heat during the wire drawing process, thereby avoiding the degradation of mechanical properties of the wire due to overheating and deformation of the mold.

3. Thermal stability: Graphite molds can withstand high temperatures of 3000°C in an inert atmosphere, and their low thermal expansion coefficient ensures their dimensional stability under temperature fluctuations. This feature makes them very suitable for high-temperature wire drawing applications such as high-strength alloy steel.

4. Ease of processing and economic applicability: Graphite materials are easy to process with precision, and various pore structures can be customized according to different applications. Its cost is much lower than that of cemented carbide, which greatly reduces production costs.

5. Chemical inertness: The chemical inertness of graphite molds makes most metal solutions unreactive, thereby effectively avoiding material contamination during the wire drawing process, especially for the production of high-end wires such as electronic-grade oxygen-free copper.

In short, the performance boundaries of graphite molds are still expanding, and it will continue to promote the wire drawing process to a more efficient and precise direction.
