The molding method is to load a certain amount of pressure into a mold having a desired shape and size and then press it from the upper or lower position. Molded graphite has a wide range of properties in terms of mechanical strength, abrasion resistance, density, hardness, electrical conductivity, etc.Special materials can be processed economically in large quantities by pressing the graphite block close to final product size.
Isostatic graphite refers to a graphite material obtained by pressing a high-purity graphite powder in a sealed liquid environment at a normal temperature and transferring the powder by ultra-high pressure. Because the pressure in the liquid is equal on each side, it is called cold isostatic pressing. The shaped graphite has the same performance values in different directions.
Vibration molded & Extruded Graphite
Extruded graphite is produced in an extrusion process. It has a coarser grain size and a lower strength but higher thermal and electrical conductivity.
