What are the advantages of graphite electrode materials of Kunshan Yi Hui Mould Company?

Six advantages of graphite electrode materials in Kunshan Yi Hui Mould Company

First, it is fast;

Graphite discharges 2-3 times faster than copper, and the material is not easy to deform. It has obvious advantages in processing thin rib electrodes. The softening point of copper is about 1000 degrees, and it is easy to deform when heated. The sublimation temperature of graphite is about 3650 degrees, and its thermal expansion coefficient is only 1/30 of that of copper.

Second, light weight;

The density of graphite is only 1/5 of that of copper, which can effectively reduce the burden of large electrode EDM and is more suitable for large dies.

Third, the loss is small;

Because spark oil also contains C atoms, high temperature leads to the decomposition of C atoms in spark oil during EDM, forming a protective film on the surface of graphite electrode, which compensates the loss of graphite electrode.

Fourth, no burr;

After the copper electrode is processed, it needs manual cleaning to remove burrs, while after the graphite is processed, there is no burr, which not only saves a lot of costs, but also makes it easier to realize automatic production.

5. Easy polishing;

Because the cutting resistance of graphite is only 1/5, it is easier to grind and polish by hand;

Sixth, the cost is low;

Due to the rising price of copper in recent years, the price of same-sex graphite is lower than that of copper in all aspects. The price of universal graphite products of Oriental Carbon is 30% to 60% lower than that of copper with the same volume, and the price is more stable with little short-term price fluctuation.
