Specialty Graphite---Isostatically Molded Graphite (IMG series)
IMG series graphite materials are produced by the method of Cold Isostatic Pressing (CIP). The CIP method involves transmitting a pressure with a liquid; in other words, it is a method of applying Pascal¨s law to powder molding. When powder is scaled in a rubber bag that has little transformation resistance and liquid pressure is applied. All of the powder surfaces receive the same compressive force equal to the liquid pressure so that the powder is compressed and molded isotropically. Our IMG series graphite materials with this method can be obtained especially fine grain, dense and uniform structure. This series graphite materials have many good characteristics such as high strength, excellent thermal shock resistance to high temperature and oxidation, low specific electric resistance, good anticorrosion, ease of precise machining, low impurities, and also have the merits of large size and good isotropy.
