Baoding Zhongda Casting Co., Ltd is a private company, locates in Wangjing town, Tang county, Hebei Province. Jingguang Railway and No. 107 National Road are close to us in the east, so the transportation is very convenient. There are 580 staff including 108 technicians in our company . And the factory covers an area of 36,000 M (the building area is 20,000M ). The main products of our company include: components automobile, machine parts (such as brake pot, brake plate, the inlet and escape pipe, gear box body, shell body, counter weight, machine cover, belt pulley, the fire fighting bolt etc.), pipe, valve body, pump body and so on. Some of them were sold well in several countries or areas such as Germany, Italy, USA, and Australia. In home we also cooperate with many famous companies in Beijing, Tianjin,Datong and other cities. Our company has three casting workshops. There are more than 100 sets of main casting machines, such as Japan SINO FBO production line, resin sand production line, molding machine production line, shoot sand core machine, electric furnaces, and cupola furnaces and so on. We have two sets of cupola furnaces (7T and 4.5T), four sets of electric furnaces (1T 2sets, 750KG 1set, 500KG 1set). Our main manufacturing methods are green sand and resin sand casting. The suitable weights range for our factory production is 5 kg to 1000kg. Japan FBO molding produce line sand case measure is 500´700 (millimeter), which is fit to produce single and large amount of products, its weight range is 5kg--50kg. Molding machine sand case is 1400 (length)´ 900 (width), the weight range is 10-- 260kg. Resin sand molding line could produce large products. The main machining equipments are CNC machining centers, NC lathes, boring lathe, vertical lathe, milling machine, grinding machine, planing machine, broaching machine, drill machine, and turning machine, etc. Also, our ordinary lathes are 220 sets, among which are 19 CNC, including horizontal and vertical CNC milling lathes (the biggest worktable of horizontal CNC machining centers is 800´800; the biggest worktable of vertical CNC machining centers is 1200´500; NC milling lathes worktable is 1700 (length)´620(width) (millimeter); the CNC machining precision is 0.02mm) and 16NC lathes, whose machining precision is 0.02mm. The physical and chemical analysis equipments include spectral analyzer (which can analyze Carbon, Silicon, Manganese, Phosphor, Sulphur elements and melting irons chemical composition), Omnipotence hydraulic pressure test machine (which can tests tensile strength, yield strength and elongation ratio etc.), Metallographic analyzer machine ( which could analyses microstructure), Ultrasonic detector (analyze interior quality of castings), and HB hardness analyzer (could analyze every ladle of melting iron). All kinds of chemical & physical records will be kept for 5 years. Sand testing analysis (can test sands moisture, gas evolution ratio, moisture absorption) will be carried out per 15 minutes. The dimension check equipment is CMM (worktable size is 1200´900). We conclude and insist on a principle of Advanced Management, refined Production, Skilled Operation, Fine Products, so the quality has improving gradually. As a result, customers in home and abroad are satistied with our products. Further more,we got the ISO9001:2000 Quality System Authentication in 2001. We would like to offer our best service to all the clients and cooperate with friends all around the world.
