Product description

In modern industry, carbon graphite parts, though unassuming, are indispensable unsung heroes in many high-end manufacturing and process industries. Molded graphite parts are industrial components manufactured by high-pressure molding of high-purity carbon raw materials in a mold. With their unique combination of properties, they are playing a crucial role in a wide range of fields, from petrochemicals to new energy.

In harsh working environments such as petrochemical and acid/alkali manufacturing processes, leaks and spills pose significant safety hazards. Molded carbon graphite parts, with their excellent chemical inertness and dense structure, have become an ideal solution to this problem. Sealing rings, piston rings, and bearings made from them can withstand long-term corrosion from strong acids, strong alkalis, and organic solvents, while maintaining stable mechanical properties under alternating high and low temperatures and high-pressure impacts. This extremely strong resistance to corrosion and creep ensures the long-term safe operation of critical fluid equipment such as pumps, valves, and reactors, significantly reducing maintenance costs.

With the advent of the clean energy era, the electrical and thermal conductivity properties of molded carbon graphite components have been pushed to the forefront of technology. In the strategic industry of hydrogen fuel cells, molded graphite bipolar plates have become a core component of fuel cell stack technology. They not only serve as the supporting framework of the fuel cell stack but also efficiently collect and conduct current, and evenly distribute hydrogen and air. Compared to traditional machined sheets, the molding process enables large-scale production, reducing costs and ensuring the bipolar plates possess ultra-thinness, superconductivity, and excellent airtightness, directly driving the commercialization of fuel cells. Furthermore, in electrochemical industries such as electroplating and electrolytic alkali production, molded carbon graphite plates are also frequently used as ideal anode materials and conductive components.

In applications where lubricating oil cannot be used or where oil contamination is likely, friction and wear pose a significant challenge to mechanical design. Molded carbon graphite components, with their inherent self-lubricating properties, cleverly solve this problem. Whether in the clean environments of textile and food processing machinery or in equipment where contact with grease is difficult, such as oxygen generators and submersible motors, carbon graphite bearings and blades provide stable and wear-resistant operation. Its low coefficient of friction and absence of "dry burning" and shaft seizure significantly improve the service life and reliability of transmission components.

From semiconductor single-crystal silicon growth furnaces to continuous casting molds in the metallurgical industry, high-temperature stability is the primary criterion for material selection. Molded carbon graphite parts can withstand ultra-high temperatures exceeding 3000℃ in non-oxidizing atmospheres, and their mechanical strength increases rather than decreases with increasing temperature. This characteristic makes them an indispensable material for withstanding high-temperature thermal fields. Simultaneously, the molding process imparts extremely high dimensional accuracy and density to the products, meeting the stringent requirements for tolerances and purity in semiconductor and precision instrument manufacturing.
