Specialty graphite (Isostatically pressed fine-grain graphites) appreciated in Electrical Discharge Machining (EDM)
Specialty graphite is becoming increasingly important for electrical discharge machining (EDM), particularly in cases where advanced design and high precision are required. Graphite material as an EDM electrode is widely used in the manufacturing of various molds, including plastic molds, die casting molds, forging molds, stamping molds, and others..
Edm electrodes made of special graphite blocks are widely used in the die and mold manufacturing market because they can reduce costs and improve quality. Compared with the copper electrode, the graphite electrode has excellent machinability and does not produce burrs, thus improving the speed of EDM.
The Fine-Grained Isostatic Graphite Developed by SHJ for EDM Electrodes:
| Grade | Bulk Density | Specific Resistance | Flexural Strength | Compressive Strength | Ash (Normal Grade) | Ash (Purified) | Grain Size | Regular Size |
|---|---|---|---|---|---|---|---|---|
| g/cm³ | μΩ.m | MPa | MPa | ppm | ppm | μm | mm | |
| IS-14 | 1.86 | 11~12 | 65 | 135 | 500 | 50 | 5 | 1200*640*270 1600*670*300 |
| IS-41 | 1.78 | 15 | 65 | 130 | 200 | N/A | 10 | 620*520*260 900*570*260 |
| IS-42 | 1.78 | 14 | 65 | 110 | 200 | N/A | 13-15 | 510*310*250 620*520*250 740*740*230 |
*The above values are typical, not guaranteed, other specification and sizes are also available.
Advantages of SHJ Graphite
