Graphite mold

1. Over 50% Improved Machining Efficiency: Graphite is easy to cut, non-stick, and does not deform. Under the same programming parameters, milling speed is 30%–80% faster than copper electrodes, significantly shortening the mold-making cycle.
2. 70%–90% Reduced Electrode Wear: Graphite is resistant to high temperatures and has strong discharge stability. EDM (Electrical Discharge Machining) wear is only 1/5–1/10 that of copper, with almost no significant wear in roughing.
3. 80% weight reduction: Graphite’s density is only 1/5 that of copper, making it easy to load and unload large electrodes, effectively preventing sagging and deformation due to its own weight, and reducing the load on machine tools.
4. 90% reduction in high-temperature dimensional deformation: Graphite’s coefficient of thermal expansion is only 1/10 that of copper, resulting in minimal deformation after discharge heating, making it easier to control high-precision cavity dimensional tolerances.
5. 30%+ Higher Current Withstand: Graphite allows for higher discharge parameters, resulting in higher etching efficiency and significantly better processing efficiency for deep cavities and large-area workpieces compared to copper.
6. 40%–60% Savings in Overall Consumable Costs: Graphite raw materials offer high cost-effectiveness, and discarded electrodes can be refurbished and reused, resulting in a high recovery and reuse rate. Long-term operating costs are far lower than those of copper electrodes.
