As a direct source factory, Xinruida specializes in the development, production, and custom machining of high-purity and isostatic graphite materials. We are dedicated to providing stable-performance and highly reliable supply chain solutions for global vacuum high-temperature furnaces, semiconductors, packaging, and metallurgical industries.

Molded Graphite

The molding method is to load a certain amount of paste into a mold having a desired shape and size and then press it from the upper or lower portion. Molded graphite has a wide range of properties in terms of mechanical strength, abrasion resistance, density, hardness, electrical conductivity, etc., and can be further improved by impregnating a resin or a metal.

Technical Features: Produced via die-molding or vibration-molding processes, this material offers a well-engineered balance between mechanical strength and thermal shock resistance, providing high cost-effectiveness for large-scale structures.
Typical Applications: Ideal for vacuum furnace structural components, large thermal assemblies, and large-dimension industrial carbon carriers.

Isostatic Graphite

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.

Technical Features: Formed using a balanced cold isostatic pressing (CIP) process, this material exhibits exceptional isotropic properties (uniform performance in all directions), high structural density, and fine grain size.
Typical Applications: Widely utilized in the manufacturing of semiconductor sintering molds, photovoltaic thermal field heating elements, and intricate graphite components with complex geometries.

Key Physical & Chemical Properties
- Thermal Stability in Extreme Environments: The internal structure and mechanical strength of the material remain highly stable under vacuum, inert gas, or protective atmosphere environments, with operating temperatures up to 2500°C.
- Low Coefficient of Thermal Expansion (CTE): Features a minimal thermal expansion coefficient, ensuring that components maintain excellent thermal shock resistance during severe temperature fluctuations and repeated thermal cycles, effectively preventing cracking or structural deformation.
- High Chemical Inertness: An exceptionally high fixed carbon purity provides strong corrosion resistance against most acids, alkalis, and high-temperature molten metals, preventing unwanted chemical reactions with processed substances during operations.
