NanJing Sanchao Advanced Materials

What NanJing Sanchao Advanced Materials does

NanJing Sanchao Advanced Materials (南京三超新材料股份有限公司) is a Nanjing, China-based publicly-listed manufacturer founded in 1999 that develops, produces, and sells diamond and cubic boron nitride (CBN) superhard material tools for the semiconductor, photovoltaic, and precision manufacturing industries. The company operates two synergistic product lines — electroplated diamond wire and diamond/CBN grinding wheels — supported by a 240 mu facility with approximately 145,000 square meters of building area, and has established a wholly-owned R&D institution in Japan focused on ultra-hard material tools. Its registered capital is 114.21 million RMB, and the company has been listed on the Shenzhen ChiNext board under stock code 300554 since April 21, 2017.

The product portfolio spans precision consumables (silicon wafer back grinding wheels, silicon wafer chamfering wheels, electroplated diamond wire for silicon and sapphire slicing), adjacent equipment (silicon rod grinding and chamfering integrated processing centers, wafer thinning machines), supporting consumables (high-efficiency cutting fluids derived from German formulation technology), and precision metrology instruments. Customer-facing segments are weighted toward semiconductor wafer processing (primary), photovoltaic/solar silicon rod and ingot machining (primary), and general precision machining/auto-parts tooling (secondary), with an emerging push into third-generation semiconductor (SiC/GaN) precision manufacturing equipment and materials via subsidiary Jiangsu Sanjing Semiconductor Materials Co., Ltd.

Sanchao monetizes through direct enterprise sales of tools and equipment, with no public pricing disclosed. Revenue is generated on a one-time basis per equipment or per tool shipment, making it lumpy and tied to customer capex cycles in semiconductors and solar. Marketing is conducted via direct sales supplemented by participation in major industry exhibitions (SEMICON CHINA, CIOE, EMO Hannover, CIMT, China CNC Machine Tool Show, China International Advanced Ceramics Exhibition). The group structure comprises the parent plus three wholly-owned operating subsidiaries: Jiangsu Sanchao Diamond Tools Co., Ltd. (a 2024-designated National Specialized and Novel "Little Giant" Enterprise), Jiangsu Sanxin Silicon Rod Grinding and Chamfering Integrated Processing Center, and Jiangsu Sanjing Semiconductor Materials Co., Ltd. Headcount is reported in the 501–1,000 range, and operating geography is concentrated in mainland China with no disclosed international customer revenue.
