Import Best Quality Graphite Sheet Metal Insert — Buy in wholesale FOB from Supplier in China

Shandong Sungraf Carbons Co., Ltd produces this graphite sheet metal insert from high purity artificial and natural graphite with a carbon content of 99% or above, designed for thermal management and metalworking applications where heat dissipation and mechanical durability are critical. The insert is manufactured in Shandong province and exported through Qingdao port, with the supplier offering custom dimensions to meet specific industrial requirements. Available grades cover both standard industrial and higher purity specifications, with the graphite's layered crystal structure providing anisotropic thermal conductivity that outperforms many conventional metal heat spreaders in certain orientations.

The base material combines artificial and natural graphite sources, with the 99%+ carbon content indicating low ash and minimal impurity levels that reduce thermal resistance and prevent contamination in sensitive thermal interfaces. Graphite sheet metal inserts of this type typically exhibit in-plane thermal conductivity ranging from 150 to 400 W/m·K depending on grade and compression, with through-plane conductivity significantly lower (typically 3-10 W/m·K), a property buyers should verify against their heat flow direction requirements. The material's low coefficient of thermal expansion (typically 4-6 × 10⁻⁶ /°C in-plane) reduces thermal stress at metal interfaces, while its compressibility allows conformal contact with uneven surfaces when properly clamped.

Primary applications include die casting moulds, forging dies, heat treatment fixtures, and thermal interface components in electronics and automotive manufacturing where graphite replaces or supplements metal inserts for improved temperature uniformity and reduced cycle times. Buyers in these sectors typically source such inserts for integration into tooling systems, heat sinks, and furnace components. Trade terms mentioned include FOB and CIF options, though specific MOQ, exact lead times, and pricing require direct confirmation with Shandong Sungraf Carbons Co., Ltd given the supplier's current 0.00% response rate.

Shandong Sungraf Carbons Co., Ltd is located on Duhua Road, Qingdao, Shandong Province, China, with the postal code 266000, operating from a position within one of China's established industrial regions for carbon and graphite material production. The supplier holds a harbor trust tier designation on the platform, though this does not constitute third-party certification of manufacturing capability. Notably, the supplier displays a 0.00% response rate with zero average response hours recorded, indicating that prospective buyers should expect potential communication delays and may need to pursue multiple contact attempts or alternative channels to confirm order details, specifications, and availability.

The supplier's profile does not disclose factory size, year of establishment, workforce numbers, annual revenue, specific production capacity, or named client references, so claims about scale or market position cannot be independently verified from the listing data alone. Shandong Sungraf Carbons Co., Ltd focuses on graphite components for industrial thermal applications, with this particular listing emphasising custom dimensional capability and bulk order support. Buyers should conduct standard due diligence including requesting material certificates, sample evaluation, and direct verification of quality control processes before committing to volume orders, particularly given the communication gap indicated by the response metrics.
