Experience
20+ Years
Two decades of uninterrupted production, refining formulations and processes to deliver consistent blank quality at scale.
Discover how 20+ years of focused carbon and graphite blank production translate into reliable supply, integrated manufacturing, and application-driven engineering.
Zhongwei Carbon & Graphite Materials Co., Ltd. was founded in 2003 in Dujiangyan, Chengdu. We operate an integrated production system — from raw material batching and forming through baking, graphitization, and impregnation — producing graphite sealing blanks and carbon brush blanks for industrial buyers in China, Southeast Asia, and Europe.
Two decades of uninterrupted production, refining formulations and processes to deliver consistent blank quality at scale.
Standard catalog dimensions plus custom profiles — cylinders and rectangular blocks available in a wide range of sizes.
Density, porosity, hardness, and conductivity adjusted through formulation, graphitization temperature, and impregnation method.
Every blank passes through a controlled, four-stage production chain — ensuring traceable quality from raw material to finished product.
