Changjiang Modeling Materials (Group) Co., Ltd. (重庆长江造型材料(集团)股份有限公司, SZSE: 001296) is a Chinese industrial materials manufacturer specializing in foundry-grade coated sand, casting waste sand recycling, and hydraulic fracturing proppants for the oil and gas industry. Founded in 1979 and headquartered in Beibei, Chongqing, the company operates nine production bases across Chongqing, Hubei, Jiangsu, Sichuan, Shandong, Yunnan, Anhui, Liaoning, and Inner Mongolia, with combined annual production capacity exceeding 2 million tons of silica sand, resin-coated sand, inorganic sand, fracturing proppants, building colored sand, and recycled waste sand. The company serves over 500 customers across more than 30 Chinese provinces and autonomous regions, including automotive, motorcycle, aviation, and railway casting enterprises, alongside domestic and international oil and gas extraction companies, and has been designated as 'China Foundry Sand Industry Base' by the China Foundry Association. Its core technology portfolio spans a proprietary clear water fracturing proppant with self-expanding resin film chemistry (86MPa pressure resistance, patent-pending), eco-friendly ammonia-free coated sand, and 3D printing sand for additive manufacturing pattern making and rapid prototyping. The company went public on the Shenzhen Stock Exchange in 2021, holds National Green Factory certification, and operates through a wholly-controlled subsidiary (Shiyan Changjiang Xinchuangcai Intelligent Manufacturing Technology) that anchors its relationship with Dongfeng Commercial Vehicle's Shiyan casting operations. Its go-to-market is direct B2B sales to industrial enterprise customers with pricing handled through individual quotation rather than published rates.
