Characteristics of Isostatically Pressed Graphite Blocks

  • Isostatic graphite block is suitable for processing all kinds of conductive materials, can process complex workpiece, processing thin-wall workpiece

  • Deep narrow groove processing, micro processing has unique advantages, high processing precision, fast speed, save raw materials.


Advantages of Isostatic Graphite Block

  • 01

    In the current industrial field, with the development of economy and technology, the technical requirements for precision molds are becoming higher and higher. Therefore, isostatic graphite properties have attracted unprecedented attention in the processing of the precision carbon graphite molds, and the screening of this kind of solid graphite block has received high attention in the industry.


  • 02

    The price of isostatic graphite block material is only 15% of that of copper electrode of the same volume. At present, graphite has become a popular material for various applications, with lower cost and more stability.

  • 03

    The density of isostatic graphite block is usually 1.7-1.9g/cm3 (copper is 4-5 times of graphite). Compared with copper electrode, graphite electrode can reduce the mechanical load in this process, and it is more suitable for the application of large mold.

  • 04

    Compared with metal materials, the volume of isostatic graphite block is lower, and it has excellent machining performance.
