Toyo graphite iso - 63:It belongs to isotropic ultra-fine particle graphite with good wear resistance. It is applied to plastic molding molds. The precision processing of precision molds (bone position, rib position, surface spark pattern processing) can process the surface finish: Ra0.4 μ m

Applied to super large electrodes
Material: iso-63
Size: 800 × 600mm. If the electrode is processed with copper, EDM processing is impossible.
