With the effort of our excellent experts and professional technicians, we have an annual production capacity of 60,000 tons of ZinO.

        We now have 20 latest patented indirect process ZnO production lines which are natural gas fueled and equipped with worldwide advanced HTAC burning technology and imported key equipments; PLC is applied during the whole production process. As a result, we have achieved the particle size control during the oxidation reaction, which is a technical breakthrough in the field.

        We established a comprehensive morden enterprise management system covering from the raw material procurement and production process control to product test, logistics and customer service. Meanwhile, we have been ISO9001:2008 certified. To ensure stable and reliable products quality, we put into use the advanced lab apparatus such as Atomic Absorption Spectrometer, laser particle sizer and Surface Area Analyzer, by using which we can carry out precise analysis for the raw material and finished products.
