Can graphite electrodes be used in small die making?
Requirements of the high surface, the appearance of products are copper electrode discharge processing
The injection mold basically are washed with electric pulses, for machine processing not to (corner, ribs) need to punch, we basically is the electrode materials of graphite and copper, graphite electrode generally used for extensive escape materials (graphite texture, discharge energy is relatively large, the removal of material relatively fast. But the surface roughness is relatively large flowers.
The copper electrode used for finishing size of the copper electrode discharge speed is not fast but spent graphite electrode is relatively small
