About Hongfeng Carbon Solutions

Hongfeng Carbon Solutions is the global leader for machined graphite components. We offer a wide range of synthetic graphite's from suppliers such as POCO, Mersen, Toyo Tanso, and SGL for specialized applications, and have developed in-house numerous resins and composites to impregnate isostatic graphite materials that enhance and optimize the performance. We use exclusively isotropic graphite to provide optimal uniformity of its strength, thermal performance, corrosion resistance, and machinability. This results in a product with long-term stability and robustness.

The international business headquarters for Hongfeng Carbon Solutions is located in Hong Kong. We currently have two production campuses in China and Japan to help ensure diversified and stable operations. The Shanghai campus spans 32 acres and provides 20k sqm. (>215k sqft.) of manufacturing space that allow us to mass produce a wide range of components. The newest Tokyo campus commissioning in May 2025 provides 2k sqm (>21k sqft.) of production space and will further enhance our R&D efforts.  We operate over 240 CNC and CMM machines along with dozens of automated 2D and 3D vision systems, ultrasonic cleaning, and 10k (ISO7) clean room.

A strong commitment to R&D and innovation has lead Hongfeng Carbon Solutions to hold over 70 patents. Our research department is continuously developing new materials to always offer the most advanced performance properties across a wide range of industry applications. We are committed to provide the latest production technologies.

Hongfeng Carbon's experienced team will guide through the material selection process to recommend an optimized solution or develop a novel material. We build long-term business relationships by supporting our clients and delivering a consistent product quickly.
We follow and are certified with external review for our ISO 9001 compliant quality practices; ISO 14001 compliant environmental management; and ISO 45001 compliant health and safety policies. Certificates are available upon request.

Why We Are Passionate

Hongfeng Carbon Solutions recognizes the vital role Carbon-based materials have in advancing the technologies and quality of life for our planet. This is why we strive to develop the most advanced materials and quality manufacturing processes that our partners rely on.

Advanced Precision Machining

Advanced Precision Machining

Hongfeng Carbon Solutions provides advanced precision machining capabilities with 0.012mm (<0.0005") tolerance. Surface grinding tolerance reaches 0.005mm (<0.0002"). Our skilled technicians operate over 240 CNC and CMM machines and can produce up to 500k units per month across many different product applications.

The entire production facility is climate controlled and uses a centralized high pressure dust collection system at every workstation to maintain a safe and clean environment.

While there is some variation between different product industries, all components undergo inspection from 2D and 3D automated vision systems, as well as manual inspections to ensure zero-defect. We maintain a culture of absolute quality.
Some products may under liquid and air pressure tests to ensure zero leakage, while others undergo ultrasonic cleaning and packaging in a 10k clean room environment.
