Product Description  and  Advantages

Product Description

High Purity: Graphite materials used in premium graphite molds typically feature high purity with minimal impurities. This effectively prevents contamination of processed materials during use, ensuring product quality. For instance, in semiconductor and photovoltaic industries where high purity is critical.

Self-Lubricating Properties: Graphite inherently possesses self-lubricating properties with a low surface friction coefficient. This minimizes friction between the mold and processed material during forming, facilitating demolding. It reduces surface scratches and wear on the product, enhancing surface quality and extending mold service life.

Product Advantages

Exceptional Material Uniformity: Through isostatic pressing, the graphite exhibits highly consistent physical properties—including density, strength, and thermal conductivity—with no significant directional variations. This prevents failure caused by localized mold wear or uneven stress distribution.

High Temperature Resistance and Thermal Shock Resistance: Withstands temperatures exceeding 1600°C and exhibits a low thermal expansion coefficient. Resists cracking under rapid temperature cycling (e.g., repeated heating and cooling cycles), offering significantly longer service life than traditional metal molds.

High-precision forming capability: Graphite's inherent machinability allows isostatic graphite to be precision-machined to micron-level accuracy, meeting demands for complex shapes and intricate structures. Post-forming dimensional tolerances remain minimal.

Superior chemical inertness: Resists chemical reactions with molten metals (e.g., aluminum, copper), glass, ceramics, and other processed materials at elevated temperatures. Does not adsorb impurities, ensuring product purity.

Lightweight and Easy Maintenance: With a density only 1/3 to 1/4 that of metal molds, handling and installation are more convenient. Minor wear can be easily repaired through simple grinding, extending the overall service life of the mold.

Applications:

Semiconductor and Electronics Industry    
Thermal field components for monocrystalline and polycrystalline silicon growth, such as crucibles, flow guides, and heaters, ensure temperature uniformity during silicon melting and crystallization processes, guaranteeing wafer quality.    
As fixtures or carriers in ion implantation and thin-film deposition processes for semiconductor chip manufacturing, they withstand high temperatures and corrosive gases while maintaining high-precision positioning.

Metal Metallurgy and Casting
Used in precision casting molds for aerospace high-temperature alloy components and automotive engine precision parts. High precision and thermal shock resistance guarantee dimensional accuracy and surface finish of castings.
Serves as vacuum melting crucibles for active metals like titanium and zirconium alloys, preventing reactions between metal and mold to enhance alloy purity.

New Energy Materials Sector
Serves as high-temperature sintering molds in lithium battery electrode material manufacturing, withstanding sintering temperatures of 800–1200°C to ensure uniform density and structural stability of formed electrode materials.          

                  

High-End Manufacturing
Used as sintering molds for diamond tools, it fixes diamond particles to the metal binder under high-temperature and high-pressure conditions, ensuring the tool's structural strength and cutting performance.
Used as polysilicon ingot casting molds in the photovoltaic industry, it encapsulates silicon material and conducts heat, maintaining temperature gradients during ingot casting to minimize crystal defects.
