       Dunhua Zhengxing abrasive Co., Ltd. was founded in 1987, Ningan City, Heilongjiang Province, Zhengxing Grinding Factory. For more than 30 years, we have been doing our utmost to study and manufacture boron carbide ceramic materials. We are determined to work hard for the original intention of studying and processing boron carbide ceramics.  

       In June 1999, after attracting investment from Dunhua municipal government, the company moved from Ningan City of Heilongjiang Province to Dunhua city of Jilin Province, and settled in the economic development zone and renamed Dunhua Zhengxing Abrasive limited liability company. The company covers an area of 1.2 hectares, which was the earliest private boron carbide production enterprise engaged in the processing of boron carbide smelting and the deep processing of powder in China at that time.
