Zhongwei Carbon supplies ready-to-machine graphite and carbon blanks in cylinders, blocks, and custom forms. With 20+ years of production experience, we deliver consistent density, tight tolerances, and flexible impregnation options for sealing, electrical, and industrial OEM applications worldwide.
Two decades of focused manufacturing, vertically integrated production, and a track record of serving sealing and electrical component makers across China and overseas.
Producing carbon and graphite blanks since 2003 with deep process know-how in mixing, forming, baking, and graphitization.
Cylinders, rectangular blocks, and custom profiles in a wide range of diameters and lengths to suit different machining requirements.
Density, hardness, porosity, and conductivity fine-tuned through formulation and impregnation to match your operating conditions.
Trusted by domestic OEMs for batch-to-batch repeatability — every shipment tested for density, resistivity, and dimensional accuracy.
High-density graphite blanks for machining into piston rings, mechanical seal faces, and packing components, with resin-based or metal-based impregnation selected to suit the application.

Electrographite and carbon blanks engineered for motor brushes, generator contacts, and sliding current collectors, with resin-based or metal-based impregnation chosen to match temperature, conductivity, and load requirements.
Explore CategoryHeadquartered in Dujiangyan, Chengdu, Zhongwei Carbon has operated a vertically integrated production line since 2003 — from raw material batching through graphitization and impregnation. We supply graphite sealing blanks and carbon brush blanks to long-term industrial partners and support domestic and overseas customers with stable, repeatable production.
Graphite blanks machined into piston rings, seal faces, and packing sets for pumps, compressors, and rotary equipment.
Carbon brush blanks for DC motors, AC generators, wind turbines, traction drives, and power tool commutators.
Near-net-shape blanks supplied to machining shops that produce finished graphite and carbon parts to their own prints.
Application-specific formulation and impregnation for high-temperature, high-speed, or chemically aggressive operating environments.
Includes systems such as phenolic resin and is used to lower open porosity, improve gas-tightness, and increase mechanical strength in sealing and chemical-duty parts.
Includes copper, antimony, silver, and other metallic systems for higher-temperature, higher-load, or conductivity-critical applications.
Selection depends mainly on service temperature, sealing requirements, conductivity targets, and the actual operating environment rather than a single material name.
Grain size, binder ratio, graphitization temperature, and post-treatment can all be adjusted to meet your exact performance targets.
Send your blank requirements and our engineering team will respond with a grade recommendation, pricing, and estimated lead time within one business day.
