Baoji Huaguang Foundry Materials Technology Co., Ltd. was founded in September 1999, is located in the Middle Section on Yongcheng Avenue, Fengxiang County, the number of staff is 132, the registered capital is RMB 5000000 Yuan. The company covered 9200 KM², the legal representative person is Zhang Xinping. Baoji Huaguang Foundry Materials Technology Co.,Ltd is a professional manufacturers for new type of foundry materials, has been committing to the development and production of exothermic Insulating Riser and ceramic runner of the R & D for more than ten years and access to a number of national patents. The management of the company is in accordance with the international standard quality, the company has established a perfect quality assurance system and has the complete sets of testing equipment to ensure the 100% of the products manufactured rate. The HG insulating and exothermic riser has adopted fever, heat preservation material and adhesive materials, with modern equipment and high-tech technology produced. So it has the advantages of high density, good toughness, heat large, long heat-holding time, so as to prolong the clotting time of liquid metal, saving feeding liquid metal, reducing the cutting area, increasing the rate of qualified products, reducing cost. The ceramic tube runner has advantages of high refractoriness, erosion resistant, light and practical, easy cutting, easy to use, save the cost, so it can improve the quality of the casting and it is praised by the majority of users. The products are widely used in nuclear power, wind power, aviation, aerospace, automotive, military industry, iron and steel, rail transportation, petroleum machinery, machine tools and many other fields, suitable for all kinds of sand casting process. At present, the products are sold in dozens of large and medium-sized enterprises in the northwest, northeast, southwest, North China, such as: China Erzhong Group, Ningxia shared group, Dalian Huarui Heavy Industry, Dongfang Steam Turbine Co., Ltd., Liaoning Fuan Heavy Industry, Qinchuan Machine Tool Group, Xi'an Aero-engine Co.,Ltd, Lanshi Group, Inner Mongolia First Machinery Manufacturing Mompany, CITIC Heavy Industry, Anhui Yingliu Group, Dalian Machine Tool, Taiyuan Heavy Industry, Jinxi Machinery Group Company.
