Through more than 20 years' striving, we have become one of the leading enterprises in the same industry. Our company is devoted to researching, developing, producing and selling grinding balls, grinding cylpebs, and ball mill liner plates, which are widely used in cement, mining and chemical industries, and power plants, etc...Our manufacturing base covers 30 mu, with the standard workshop area of 12, 000 sqm. Three advanced casting manufacturing lines, and sophisticated testing equipment guarantee a stable and resistant product quality. Our annual productivity is 20, 000 tons.
Company History
In 1989, Liubang Casting Factory, as a individual, was established. We mainly used coke smelting reduction technics, and the products were casting grinding balls and bars.
In 1996, Peixian County Tongda Casting Co., Ltd. was established. We became a general taxpayer. One medium frequency furnace production line was introduced into our production, together with the annealing process technics.
In 2002, our factory was moved to Liubang Industrial Park, Peixian County, Jiangsu Province. The overall property had a qualitative improvement
In 2008, renamed as Xuzhou H&G Wear Resistant Co., Ltd...12, 000 square meters standard workshop, 3 medium frequency furnace production lines, 2 furnace annealing equipment, and 2 oil-immersed heat treatment equipment were put into production. Also, better technology and equipment was used for IQC and OQC.
In 2012, D-win Metal Material (Shanghai) Co., Ltd. was established in Shanghai, a wholly owned sales subsidiary, intending to develop international business.
In 2013, 800 square meters office building was put into use in our factory, making great progress in both work environment and employees.
