Jiangsu Jingling Casting Stock Co., Ltd., a bran-new comprehensive enterprise integrating casting, forging and mechanical manufacturing, lies in the Yangtze Delta, where the economy is advanced. Located at Weitang Industrial Park, Changzhou National High and New Technology Industrial Development Zone, Jiangsu, the company rests on Yangtze River, the golden watercourse in China, in the north, leans against Beijing-Shanghai Railway and Shanghai-Nanjing Expressway in the south and abuts on Changzhou Airport in the west, enjoying every convenient water, land and air transportation.
Covering an area of 120,000 sq. meters and building area of over 40,000 sq. meters, the company possesses total assets of 220 million Yuan including fixed assets of 140 million Yuan. At present, we have 580 employees including 180 technicians in all fields and more than 40 full-time personnel engaged in quality control and inspection
Organized basing on former Changzhou Forging Main Plant and Changzhou Casting Main Plant, the company has over fifty-year production history, and is the Key Backbone Enterprise Manufacturing forgings of the former State Bureau of Machine Building Industry, Specialized Casting & Forging Center in Jiangsu Province and Member Unit of China Forging Industry Association and China Foundry Association. Especially through the construction of new plant and technical innovation for about two years, the company has become the domestic casting and forging base with higher popularity, moreover, in fields of die forging and resin bonded sand casting, our existing equipments and technical level have kept ahead of other follow traders in the country.
The company administrates four professional manufacturing plants as forging plant, casting plant, machinery plant and Changjiang Forging plant, which mainly manufacture various steel die forgings for auto connecting rods, steering engines, gears, driving shafts and vehicle axles, open die forgings, gray cast ironware, nodular iron castings, digital-controlled lathes and complete mechanical equipment. The registered trademark is “Jingling”. We are capable of not only producing forgings of 18,000 tons, castings of 20,000 tons and digital-controlled lathes of 500 sets, but also designing and developing complete set of relevant mechanical equipments. Besides, we have passed ISO9001:2000 Quality Management System Certification and QS900 International Standard Certification.
The company has nine die forging production lines such as 2500ton die forging press, imported 10t·m hydraulic air hammer, 2t and 5t die hammer and so on. All die hammers adopt German damping device, forging heating adopts the advanced KGPS medium-frequency heating techniques, so it has advantages of rapid heating speed, equal temperature, little thermal radiation, high precision of forged piece, good surface quality, clean working environment and environment protection, etc, forging precision can achieve and exceed DIN7526E standard, in addition, normalization of forging adopts the advanced continuous-type isothermal normalizing automatic production line, so the quality of forging ranks the superior level in the country.
Casting plant of the company has two set of 10t/h resin bonded sand treatment systems, six 10-25t/h mixing mills, one DISA3030 Disa automatic molding line and matched German BWD sand treatment equipment, two 5t American “Inductotherm” electric furnaces, two 7t automatic charging-type cupolas and other large casting equipments. Therefore, casting production can achieve centralized control and advanced techniques of automatic charging cupola and electric furnace dual melting, and thus QT400-QT800, HT200-350 and diversified alloy castings can be melted, max. unit weight of casting produced can reach 30 tons, and large-scale shot-blasting room can accomplish the shot blasting of large casting in 9×4.5×2.5m, by doing so, inside and outside surfaces quality of medium and large pieces is greatly improved, surface roughness can reach Ra12.5-50 and precision of casting dimension can reach CT8-12 grade. Furthermore, large-scale table fuel temper furnace in 9×2.8×2.2 can achieve the heat treatment on various castings, and product quality ranks the superior level in the country, quality of the export product achieves the level of international first quality.
Machinery plat of the company has more than 80 mechanical machining equipments and eight digital-controlled centers. CK75 serial digital-controlled lathes developed by the plant adopts Fanuc digital-controlled system, 45°inclined lathe bed, servo motor and ballscrew driving, linear rolling guide rail, automatic chip removal and full safeguard structure, characterized by high precision, good dynamic stiffness, strong shock resistance and rapid transposition of cutter frame, etc, this products belongs to the domestic digital-controlled machining equipment with leading technology.
Changjiang plant of the company has not only 15 sets of free-forging production equipments, but also main equipments of 3t, 1.5t and 1t free forging hammers. Product quality continuously keeps the leading level in the industry.
On product testing, the company owns advanced testing devices such as direct reading spectrograph imported from Germany and complete physical and chemical analyzing and testing as well as flaw detection equipments, thus test data is rapid and accurate. In addition, the company is capable of designing and developing computer three-dimensional shaping and manufacturing series of digital-controlled machining center. Now ERP office automation system has operated in the company.
