ZHIMO(Shanghai) New Material Technology Co., Ltd grew out of Shanghai Grinding Media Factory and since the beginning of nineteen nineties, we have long been involved in the R & D and production for the zirconia grinding beads and now we are one of the few manufactures developing from that period. In 2013, in order to adapt to the development of chemical industry, we had bravely finished a stock reform and restructuring. We started to cooperate with German leading zirconia beads manufacturer and ZHIMO was born at that time. Now ZHIMO has been concentrated on the research of all kinds of ceramic products, such as ziroconia beads, alumina balls, silicon nitrade balls, zirconia ceramic parts, alumina ceramic parts and ceramic grinding mills. Our special forming process of roll polishing ensures good spherical shape and high density for the zirconium grinding beads. Advanced kiln sintering technology and long-time high-temperature fritting ensures stable performance of the zirconium beads in use process. We now have long term business partners in more than 20 countries and we always enjoy a good reputation in the market. Under the strong global economic competition, we always work with the business objective "quality first, customers supreme" and reward all our customers with continuous support.
