Nantong Hengli Heavy Industry Machinery Co., Ltd. was founded in 1952, formerly known as Hai'an County Heavy Machinery Factory. It is a professional factory designated by the former Ministry of Machinery and Electronics Industry to produce rolling machines. It is a high-tech enterprise in Jiangsu Province, a technology intensive and knowledge intensive enterprise in Jiangsu Province, and an AAA level contract abiding and trustworthy enterprise in Nantong City. The company has passed the national metrological assurance confirmation and ISO9001 quality system certification. The company has been specializing in the production of rolling machines since 1976, with a history of over thirty years. The company's main products include rolling machines, leveling machines, press machines, etc. It is a technology-based enterprise that integrates scientific research and production, and has strong capabilities in undertaking various mechanical equipment manufacturing. It has a high reputation in the domestic and foreign industries. Our products cover the whole country, with a market share of 45%, and are exported to more than 20 countries and regions including Japan, Russia, Southeast Asia, the Middle East, and Africa. Nantong Heavy Industry Machinery Co., Ltd., as the parent company, established three subsidiaries in 2001: Nantong Hengli Heat Treatment Co., Ltd. (holding), Nantong Hengli Casting Co., Ltd. (holding), and Nantong Hengli Head Co., Ltd. (holding). In 2008, Nantong Hengli Heavy Industry Equipment Co., Ltd. (holding) was established to further improve equipment level and expand production capacity. The company currently has three factory areas, covering a total area of approximately 150000 square meters, with a factory area of approximately 55000 square meters. The company has a maximum lifting capacity of 150 tons and is equipped with facilities such as HTM-50GME gantry machining center, TAK6920 CNC floor boring and milling machine, T6920 floor boring and milling machine, φ 160 floor boring and milling machine, HTII160 × 160/32Q-NC CNC heavy-duty horizontal lathe, 4 × 20 meter CNC cutting machine, φ 1100 * 10M well furnace, large shot blasting and dust removal machine, and large annealing furnace. The company has strong technical strength, strong ability to develop new products, and high employee quality. There are a total of 332 employees, including 103 scientific and technological personnel with college degrees or above, accounting for 31% of the total number of employees, including 56 with intermediate and senior professional titles; A technology development center has been established, with a team of lean, refined, and technically skilled R&D personnel. There are 36 technical personnel directly engaged in product research and development, accounting for 10.8% of the total number of employees. After a joint venture with Marubeni Corporation and Kurimoto Iron Works in October 1995, with the introduction of Japanese funds, a large assembly workshop with an area of over 10000 square meters was built in the northern Jiangsu region, and some key equipment was added, greatly enhancing the company's manufacturing capabilities. At the same time, by introducing Japan's CNC universal bending machine technology, its technological advantages are: (1) the application of advanced NC and CNC numerical control technology makes it possible for the bending machine to be CNC controlled, greatly improving efficiency, which is three times that of general products; (2) Using curved upper rollers and supplemented by idler rollers to achieve high straightness of the product Special rolling process - rear bending (Japanese patent), which enables the product to achieve high roundness; ⑷ Breakthrough in small diameter (usually the diameter of the small coil in domestic plate rolling machines is 30-40 times the thickness of the plate, firstly, under full load, the diameter of the small coil reaches 16.5 times the thickness of the plate, and secondly, under normal load, the diameter of the small coil is 1.12 times the diameter of the upper roller); ⑸ The overall structure is easy to move and does not require installation. The company attaches great importance to technological innovation, development, and reserves. It has established a joint development center with Beijing Institute of Mechanical and Electrical Research and a graduate station at Nantong University. It adheres to the path of combining production, learning, and research, and cooperates with universities such as Southeast University to research, develop, and produce high-tech products. It has established horizontal connections with many universities and large enterprises such as Xi'an Heavy Machinery Research Institute and Sichuan Deyang Erzhong to enhance its technological development efforts. The company's annual expenses for new product research and development reach more than 5% of its sales revenue. By implementing measures such as heavy rewards to widen the income distribution gap and fully mobilize the enthusiasm and creativity of scientific and technological personnel, as well as establishing an assessment and elimination mechanism, we strive to achieve both pressure and motivation, and more vitality. We strive to create a working environment that respects knowledge and talent, and strive to create a work atmosphere that respects entrepreneurship. The awareness of innovation among technology personnel is constantly increasing, and the speed of new product development is significantly accelerating. In recent years, we have digested and absorbed advanced technologies at home and abroad, developed and produced a series of CNC bending machine products with independent intellectual property rights and international advanced level. We have developed and designed more than ten varieties of bending machines (three roll symmetrical bending machine, asymmetric bending machine, horizontal downward adjustment bending machine, hydraulic four roll bending machine, upper roll universal bending machine, corrugated pipe bending machine, marine bending machine, special trailer bending machine, large ultra wide upper roll CNC universal bending machine, large ultra thick upper roll CNC bending machine), with more than 600 specifications, thickness ranging from 2 millimeters to 270 millimeters, width ranging from 500-17000 millimeters, and produced W11ST&B&B bending machines. NC-80 * 3000 CNC universal plate rolling machine, W11STNC-35 * 17000 large ultra wide upper roll CNC universal bending machine, W11STNC-180 * 3200 large ultra thick upper roll CNC universal bending machine, W11XNC-270 * 3500 fully hydraulic CNC horizontal adjustment bending machine. The company has developed and designed W43- (6-100) * (1000-13000) high-strength leveling machines. The company has developed and designed various types of hydraulic presses, and introduced the high-precision friction press design and manufacturing technology of forging equipment with market potential from Japan's Kurimoto Iron Works, enriching the company's development momentum. The company has independently developed and produced a super large CNC marine three roll plate rolling machine (with a plate thickness of 40mm and a plate width of 21m) through research and development, drawing on advanced international manufacturing technology for ultra large marine CNC plate rolling machines. The structural type and control level have reached the advanced level of similar international products. This project has been listed as a 2007 Jiangsu Provincial Science and Technology Key Project by the Jiangsu Provincial Department of Science and Technology. On January 4, 2005, the "Large Ultra Wide Universal Rolling Machine" was signed as a scientific and technological achievement organized by the Jiangsu Provincial Department of Science and Technology; And obtained three national patents: ZL200520076691.X upper roller connection device for large beam bending machine, ZL200520076692.4 upper roller movable bending machine ZL200520076690.5. In 2006, the large-scale ultra wide universal rolling machine was included in the Jiangsu Province's 2006 National Key New Product Plan. The large-scale ultra wide universal rolling machine won the second prize of Nantong Science Progress Award in September 2005 and the third prize of Jiangsu Science Progress Award in May 2006.
