Description
Fine Grain Isostatic Graphite Block
Isostatic graphite, a fine-grain graphite material manufactured through an isostatic molding process, shines in a number of industrial sectors with its outstanding performance characteristics.
features
With its uniform organization and high density, it exhibits incredible strength and has a low coefficient of thermal expansion for excellent thermal stability. What's more, isostatic graphite block is isotropic, a characteristic that allows it to perform consistently in a variety of applications. Therefore, isostatic graphite is widely used in semiconductor, photovoltaic, metallurgy, glass, ceramics and many other fields.
Applications
EDM
In electrical discharge machining (EDM), specialty graphite is commonly used for electrodes due to its unique advantages. Its outstanding performance is reflected in the following aspects:
Firstly, isostatic graphite exhibits excellent thermal shock resistance, allowing it to remain stable and resistant to damage in high-temperature environments. Secondly, graphite has an extremely low coefficient of thermal expansion, ensuring precision in machining. Additionally, graphite possesses good machinability, enhancing the efficiency and precision of electrode processing. Most importantly, graphite exhibits a very low wear rate during the EDM process, significantly extending the electrode's lifespan.
We understand that each customer's EDM application requirements are unique, so we are able to recommend cost-effective graphite materials based on their specific needs. Whether it is roughing or finishing, we can provide suitable EDM graphite electrode materials. These materials not only boast high density and a good surface finish but also possess excellent mechanical properties, effectively improving the electrodes' service life.
Hot Bending Molds in Glass Production
Isostatic graphite has significant advantages in processing glass hot bending molds. Firstly, it does not cause damage when it comes into contact with hot glass, ensuring a smooth process. Secondly, it has excellent heat and impact resistance, and can maintain stability under high temperature and impact environment. In addition, isostatic graphite has self-lubricating properties, which can reduce the friction of the mold in the processing process and improve the processing efficiency. At the same time, its wear resistance is also very good, helping to extend the service life of the mold. Finally, the use of isostatic graphite processing glass hot bending mold can also improve the surface finish of the glass, so that the finished product is more beautiful.
In addition to being able to supply graphite materials, SHJ is able to offer a complete solution for high temperature treatment in the glass processing industry, based on its expertise in carbon/carbon composites and carbon fiber mat insulation.
Casting
Isostatic graphite is widely used as a graphite crucible in continuous casting crystallizers for copper alloys and in precious metal casting processes.SHJ fine-grained isostatic graphite is particularly suitable for metal casting processes.
Its advantages include a low coefficient of thermal expansion (CTE), dimensional stability, and ease of machining to a polished surface. In addition, it has excellent thermal conductivity, chemical and heat resistance, and high strength.
Silicon Wafer Manufacturing

Select graphite grade according to application requirements: Choose materials for manufacturing sintering molds based on working temperature and pressure requirements. SHJ, in collaboration with metallurgical professionals for decades, can assist you in selecting the appropriate graphite material grade for this field.
Heat Treatment
The thermal conductivity of graphite is very high, but its coefficient of thermal expansion is very low. These properties give graphite excellent thermal shock resistance, so isostatic pressed graphite materials are widely used in vacuum furnaces, induction furnaces and other heat treatment applications. For example, it can be used to make heating elements in furnaces.
In heat treatment applications, SHJ combines its strengths in carbon-carbon composites to provide customers with comprehensive graphite solutions.
