In general, carbon is produced by carbonizing mixed coke substances with pitch binders in a baking furnace. When this carbon is graphitized in an electric resistance furnace, the amorphous carbon structure transforms to crystalline graphite. This is called Graphite.
CIP (Cold Isostatic Pressing) is a method of cold hydrostatic pressure molding usually known as “rubber press”. We have one of the largest rubber-press molding containers in Japan with an inner diameter of 98″~h118″ (2,500mm to 3,000mm) .
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 sealed in a rubber bag which 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.
There are three types of graphite designated by the production method: Isotropic, Extruded and Moulded.
