Isostatic Graphite

Fine grain cool press graphite material is a new type material which is widely used in the lastest fifty years.This kind of graphite materials  have many super properties such as good electric conductivity,heat conductivity,high strength of high temperature resistance,self lubrication and high bulk density and easily machining, etc.It is more used in every field of today's industrial area such as monocrystal silicon,electric spark machining(EDM),metal continuous casting,high temperature corrosion resistance container, special purpose and so on.

Isotropic graphite(Fine structure large specification isotropic graphite)is produced by isostatic compaction technology,it has not only all properties of high purified graphite,but also has good isotropism. Its properties are connected with size,shape nd sampling orientation,its structure is homogeneous, fine and close,its mechanical strength is high, its oxidation resistance capacity is very strong.

The graphite used in Machining of electric spark ,its consumption is only 1/3-1/5 of copper materials. Its machining capabilities are all right and so much advantages.It can be said that is the best material among graphite materials.

As one manufacturer of isostatic graphite,we adopted the newest home and abroad technologies. The graphite is produced with following equipments:
1)All automation electric burden system
2)Forced mixture system
3)The largest scale 125000T isostatic press
