Shanghai Hudong Electric Carbon Co., Ltd., formerly known as Shanghai Hudong Electric Carbon Factory, was established in 1993. In 2002, it was relocated from the plot near Shanghai Pudong Hudong Zhonghua Shipyard to Fengxian New Area of Shanghai Free Trade Zone, and was transformed into a limited liability company. A standardized professional production enterprise with comprehensive carbon graphite product manufacturing technology and equipment, mainly produces various types of brush holders for motors, brushes, electric slides/points, sliders and carbon products for machinery.

Production capacity: The unit covers an area of 14,930 square meters, and the construction area of the workshop and other buildings is 5,500 square meters. The company has a full set of equipment for producing brush blanks, 500 liters, 100 liters, 40 liters of kneaders, Ф360, Ф160 sheet rolling machines, 500, 250, 200, 100, 66 tons four-column hydraulic presses, 45kw muffle sintering electric furnace, 3R Milling machine, mixing machine, 350kw DC current and 10 Acheson graphitization furnaces, bell-type resistance furnaces, complete brush processing equipment and mechanical processing equipment such as turning, milling, planing and band sawing machines, 500kw high pressure Power distribution room and environmental protection equipment and related professional testing equipment. The company's annual production capacity of brush blanks reaches 200 tons. The annual brush processing is more than 1 million pieces.

Technical capability status: There are seven senior and intermediate professional engineering and technical personnel, most of whom have held technical leadership positions in the technical and quality inspection departments of large-scale electric carbon plants, and played an important role in the development of new products and product quality control for enterprises.

Quality assurance system status: The company is equipped with full-time quality inspection management personnel, which strictly inspects the purchase of raw materials and all aspects of production. It has a blank production line, assembly line and finished product processing line that adopts self-inspection, special inspection, first and irregular sampling inspection phases. Combined with the inspection system, each measuring instrument is regularly submitted to the measuring department for verification every year, and the physical and chemical testing methods are perfect. 100% testing is carried out on important products such as railway brushes. The company has obtained the quality management system certification of the Shanghai Quality System Audit Center, GB/T19001 -2016/ISO9001:2015 certificate registration number 00317Q30303R5M.

Existing production products and technical quality status: Supporting products with large enterprises such as Shanghai Baosteel Group Corporation and Shanghai Chlor-Alkali Chemical Co., Ltd., and a large number of replacements for brushes used in imported large-scale equipment motors, and jointly developing large-capacity conductive for Shanghai Baoshan Iron and Steel Plant Roller brushes and D380 series of large-scale steel electromechanical electromechanical brushes. These products have better technical performance than imported brushes, and have obtained a number of national patent technology certificates. In the field of railway brushes, the company used to be a designated production unit that had obtained approval from the Transportation Bureau of the Ministry of Railways. Supported 8 types of carbon brushes for Shaoshan series traction motors for Zhuzhou Electric Locomotive Factory, Chengdu Locomotive and Rolling Stock Factory, Datong Locomotive Factory, Zhuzhou Jiufang and Yongji Motor Factory, which were confirmed in technology and type test performance, and were obtained by CRRC Group ( Former Ministry of Railways) Use evaluation of each unit. All the brushes supplied above meet the national standards and the quality standards and other technical requirements stipulated in the material procurement bids of the supporting plants. In general, the brushes supplied by the company have good performance in commutation, low wear and protection The advantages of the motor roller copper bar, etc., are these, so it has obtained a good evaluation from many users. And more locomotive depots supply a variety of brushes. All the brushes supplied above meet the national standards and the quality standards and other technical requirements stipulated in the material procurement bids of the supporting plants. In general, the brushes supplied by the company are In terms of performance, it has the advantages of good commutation, low wear, and non-wearing motor commutator. These are the reasons why many users have obtained good evaluations.
