The graphite product is one of the few dual - used materials and specializes in the production technology of oxygen - Free copper rod. It includes a graphite tube furnace and a graphite crystallizer. Graphite MoldThe Graphite Mold is manufactured in a precise manner to allow proper and smooth introduction of the oxygen - free copper rod. These features make this mold suitable for this application as graphite has very good heat - resistance high thermal conductivity and good chemical stability. It resists the high temperature from the copper rod production process without deformation or degeneration. This graphite mold ensures the output of oxygen - free copper rod with uniform sections and a high degree of purity.
